Hi team,
Today I opened comfyui desktop and it told me to update, after updating I find ComfyUI-Manager menu on top screen disappered. So I checked around on Internet and download this repo like
C:\Users\rj\Documents\ComfyUI\custom_nodes\comfyui-manager.When I restart comfyui desktop there is still no comfyui-manager on screen
Console log like this, please help! Thanks

Rename AppData\Local\Programs\ComfyUI\resources\ComfyUI the file manager_requirements.txt
and Check the ComfyUI-Manager in AppData\Local\Programs\ComfyUI\resources\ComfyUI\custom_nodes
recreate Comfy and go
@Rafeedy commented on GitHub (Dec 10, 2025):
sorry to be a bit slow, but, Rename waht to what? this "comfyui_manager==4.0.3b4" is written in the manager_requirements.txt and ComfyUI-Manager folder exsist and has all the files in it, so when you say rename?! what does that mean?
@iPyGuy commented on GitHub (Dec 10, 2025):
Same thing here, it just disappeared. Now I only have a red X in its place.
This isn’t the same thing, it’s just a menu for installing extensions but doesn’t provide any of the other features, such as enabling previews.
@jmorbit commented on GitHub (Dec 11, 2025):
Same issue here, Manager missing and I can no longer Drag and Drop Workflow PNG's or JSON files, it gives me the no symbol, circle with a diagonal line through it.
@MeihuaZhouzi commented on GitHub (Dec 11, 2025):
me too too too too too too
@changpd25-cell commented on GitHub (Dec 11, 2025):
Me too. The extension manager under the menu is of no use. It won't show the missing nodes or the conflicting ones. For me, this function doesn't have any effect in resolving node failures. I hope this problem can be fixed.
@lucasye2008 commented on GitHub (Dec 11, 2025):
The same issue.
@TheimKomm commented on GitHub (Dec 12, 2025):
same here
@Rafeedy commented on GitHub (Dec 12, 2025):
I really miss my Manager, so we are just sitting tight untill the fix is out?!
@NiFonta commented on GitHub (Dec 12, 2025):
Hi, sorry. I have move the file in other location, and reboot comfy,
Remember to leave the old manager in the usual custom node, sorry i'italian,
Ps: try to boot comfy first and see the manager reappear, it worked for me. I'm not home now, but let me know if it worked.
@Rafeedy commented on GitHub (Dec 12, 2025):
thanks for trying, but i am unsure of your instructions,
@dsdoll commented on GitHub (Dec 13, 2025):
same issue,
@Kyricus commented on GitHub (Dec 13, 2025):
Add me to the list, I've had this problems since the last update. I've tried numerous fixes, re-installed the manager, tried the manager under the C menu, nothing.
@TrevorNewsome76 commented on GitHub (Dec 13, 2025):
Same here :(
@tmaiaroto commented on GitHub (Dec 13, 2025):
I think it also removes custom nodes too. I thought this was just the UI, but my node library has many custom nodes missing. I can't search to find them either. Even though they are in my custom_nodes directory. I think these last updates essentially ended ComfyUI. I hope they fix this soon. It's currently an unusable tool for me, that's just how important custom nodes (and the manager) are :(
@lucasye2008 commented on GitHub (Dec 14, 2025):
I want the manger be back. It's essential and very helpful for installing missing nodes and updating nodes usually.
@bluesnow2026 commented on GitHub (Dec 14, 2025):
me 2. I miss manger
@dhawgood commented on GitHub (Dec 15, 2025):
this is clearly really annoying.... reinstate the manager as it was and stop messing with things that don't need updates
@LV-Soft commented on GitHub (Dec 15, 2025):
This is what I did and it worked for me:
I renamed the file
AppData\Local\Programs\ComfyUI\resources\ComfyUI\___manager_requirements.txt(I’m not really sure if this made a difference), then I renamedC:\Users\YourName\Documents\ComfyUI\.venvtoC:\Users\YourName\Documents\ComfyUI\__old__.venvjust to keep it as a backup — if everything goes well, you can delete it later.Start ComfyUI and it will ask you to recreate the virtual environment; confirm that you want to do it. If you have multiple Python versions installed, you must use the same version you originally used to install ComfyUI, otherwise it won’t work.
Once the virtual environment finishes creating, ComfyUI will start normally and the Manager buttons and everything else will appear as before.
Before doing anything else, go to Manager → Custom Nodes Manager, filter by “installed”. You’ll see some nodes that say “Import Failed” or something similar. For each one, click “try fix” and restart — do this one at a time.
If during any restart ComfyUI throws an error and doesn’t start, it’s likely a permissions issue. Most likely a Python process was left running, and you need to close it from the Task Manager (this may happen once, twice, or not at all — mentioning it just in case).
After you finish fixing all nodes marked as “Import Failed”, you may notice that some nodes in your workflow say they are not installed. At that point, simply go to the node in the Manager, click Update the node, and they will work again — everything should be back to normal.
@CoastKid commented on GitHub (Dec 15, 2025):
Please bring back classic manager! Also missing Model Manager part a lot.
@samooca commented on GitHub (Dec 16, 2025):
le dot.
@Musigreg commented on GitHub (Dec 16, 2025):
Everyone... For the previews, they changed the location of it!
(Thank you for the warning, devs!!)
.
(Don't search preview, it's hidden within the search for "Method")
@HarounAttia commented on GitHub (Dec 16, 2025):
this worked for me too
@greheenlp commented on GitHub (Dec 16, 2025):
rename this AppData\Local\Programs\ComfyUI\resources\ComfyUI___manager_requirements.txt
and C:\Users\YourName\Documents\ComfyUI.venv
this worked for me too, thanks.
@Summersunset6698 commented on GitHub (Dec 16, 2025):
Thank you! This worked for me :3 And renaming manager_requirements.txt was indeed essential. Thank you so much! Now if only they'd stop breaking stuff :P
@One-With-The-Freaks commented on GitHub (Dec 16, 2025):
Yes, manager_requirements.txt is essential, BUT you do not need to delete/rename your whole .venv.
This worked for me...
and just delete the 'comfyui_manager' folder and the 'comfyui_manager-4.0.3b4.dist-info' folder (that's why Step1. is crucial), instead of deleting the whole .venv!
@nelloxx-eng commented on GitHub (Dec 17, 2025):
Worked perfect! Thank you!
@NightKillers101 commented on GitHub (Dec 17, 2025):
Worked perfectly, thank you, I was so sad to see the manager button gone after the update.
@jlpilkin commented on GitHub (Dec 18, 2025):
Deleting manager_requirements.txt gives me a missing Python packages error that just hangs whenever I tell it to reinstall packages. Instead, if I edit manager_requirements.txt and delete the entry starting with "comfyui_manager", the application now loads with the UI.
@theshubzworld commented on GitHub (Dec 18, 2025):
Delete ComfyUI Manager from:
C:\Users\YourProfile\AppData\Local\Programs@comfyorgcomfyui-electron\resources\ComfyUI\custom_nodes
Clone the latest version:
git clone https://github.com/Comfy-Org/ComfyUI-Manager.git
Rename
manager_requirements.txtto_manager_requirements.txt.Delete the following manager files from
.venv\Lib\site-packages(the version may be different):
Restart ComfyUI.
If you get an error asking to recreate Python or the
.venv, back up the previous.venvand let it recreate everything.Once it is done, you can restore
Lib\site-packagesfrom the old.venvjust for testing.After that, you can restore the entire old
.venvagain.This worked for me. I had to overwrite the existing environment and skip the files that were already present. and again i just switched to backed up .venv and it worked.
@king820616 commented on GitHub (Dec 19, 2025):
So how do you operate Windows Portable?
@zacharisharris commented on GitHub (Dec 20, 2025):
How does this quick fix apply to the macOS desktop app?
@One-With-The-Freaks commented on GitHub (Dec 20, 2025):
Do not waste your time with the qorkarounds, cause they do not properly work. Finally, comfyui released some information on the topic. you can easily switch back to the old manager via a button in the settings menu.

What a clusterfuck of an update this was!
@HammadRafique29 commented on GitHub (Dec 21, 2025):
If anyone wanted to move to back the previous manger enable
Use lagacy manger UIserver-config/use-lagacy-manager-url@Athari commented on GitHub (Jan 4, 2026):
Should I be concerned that my log still contains this:
This is a fresh install of ComfyUI. I switched to "legacy" manager to get installation from Git (which didn't work...).
@One-With-The-Freaks commented on GitHub (Jan 8, 2026):
Afaik, this is a correct but misleading message, at least when using the comfyui desktop version (aka electron), since there is a version difference to the github verfsion of comfy, which is always newer. Since the desktop version is not as up-to-date with standard fork, this message shows up.
I have the same in my comfy desktop and stopped caring - everything seems to work fine.
But I don't understand what you mean here:
"I switched to "legacy" manager to get installation from Git (which didn't work...)."
Flicking said switch will NOT clone the legacy manager's github repo into custom_nodes, but will use an already integrated version of the legacy manager.
Hope this helps somehow.
@Athari commented on GitHub (Jan 9, 2026):
@One-With-The-Freaks
Thanks for the info.
What I meant is that I needed the now "legacy" feature of installing custom nodes from Git URL (and that thing failed so I installed the nodes I needed manually).
