Original GitHub issue: https://github.com/open-webui/open-webui/issues/8803

I've installed Open WebUI in a conda environment using pip. So no docker image. It's worked well for months!

After upgrading to a newer version of Open WebUI, using pip upgrade as recommended somewhere, Open WebUI no longer works (internal error 500).

If I make a new conda environment and start from scratch, what files do I need to copy over from the old conda environment in order to preserve users and chat histories?

Currently ~/miniconda3/envs folder has two folders openwebui and openwebui2. I.e. the old environment that no longer works, and the new environment with a fresh installation of Open WebUI.

Inside each of the environment folders we have:

drwxrwxr-x  3 openwebui openwebui 4.0K Oct 31 08:15 x86_64-conda-linux-gnu
drwxrwxr-x  3 openwebui openwebui 4.0K Oct 31 08:15 x86_64-conda_cos7-linux-gnu
drwxrwxr-x  3 openwebui openwebui 4.0K Oct 31 08:15 man

drwxrwxr-x 10 openwebui openwebui 4.0K Oct 31 08:15 share
drwxrwxr-x  9 openwebui openwebui 4.0K Oct 31 08:15 include
drwxrwxr-x  2 openwebui openwebui 4.0K Oct 31 08:15 compiler_compat

drwxrwxr-x  3 openwebui openwebui 4.0K Jan 23 07:55 bin

but I can't figure out where the user data is located.

If anybody has ideas for the salvaging the old installation, here are the error messages within the original Open WebUI console, after upgrading:

Bad Request on websocket - did you configure websockets yet on a reverse proxy (assuming you use one?)

also it should be in the lib folder, then python folder, then open_webui, then data, there you should find database and other stuff

So awesome! Thanks!!

I'm not using reverse proxy. I have sometimes accessed the Open WebUI on this machine remotely through an ssh -L tunnel, but that's it.

OK, so after copying the data, I see I'm having the same error in the new install.

Then after making a third blank install I still see the same error.

Then when opening an anynymous brower tab, it does work!

I guess browser cache has to be completely cleared before a new version of Open WebUI works.

But now, even after getting it to work, it's not seeing my ollama models in the workspace, so I can't configure new models:

But I can still select between existing models in when starting a new chat:

What do you think is wrong?

The "base"-models have moved to the admin section only and should be visible for you there.

The Models in the workspace section are only for custom models (like Custom GPTs) that are based off of a base model like deepseek-r1 but have special system prompts or special descriptions, a custom picture and just different things whatever you set them to.

This was done quite a while ago. Basemodels: admin section. Custom models: workspace.

Check in admin section if you see your base models there.

So cool, I love this change! It's way more intuitive.

But the browser cache thing is a bummer. I've replicated it over multiple systems.

I guess it makes sense for the browser cache to get glitchy after a major web site update, but I wish there was a smarter solution than asking all the users to reset their browser cache manually. I don't know if cache expiry settings can on Open WebUI assets can be optimised further, somehow.

Anyway, thanks for the help, @Classic298. That was awesome!!

Yes the browser cache is indeed an issue. Users should just do a STRG+SHIFT+R after updates to ensure cache gets deleted. That fixes it all.

I don't know how to fix this though. Perhaps with some reverse proxy settings in nginx, nginx can tell the browser to only keep the cache for x minutes or something? I will do some research into this.

@shiraz-shah

If you use a reverse proxy like nginx (which is IMO recommendable to use), you can set a custom cache policy, which the browser adheres to, which ensures the cache of the website is only stored for x hours before being invalidated/deleted by the browser.

I think this might be a solution to this issue and users will not be forced to delete cache manually everytime.

Obviously, choose a long enough time to still take away load from the OpenWebUI service, but at the same time, short enough so if you DO update (e.g. at the end of a work day) so that the next day, the cache is gone again/invalidated and users can use the service normally, because the browser has deleted the cache for you already.

Or you can also choose something like 30 minutes of course.

# Static Assets - Cached for 7 days
location ~* \.(css|jpg|jpeg|png|gif|ico|svg|woff2?|ttf|eot)$ {
    expires 7d;
    add_header Cache-Control "public, max-age=604800";
    try_files $uri =404;
    access_log off;
    log_not_found off;
}

This will cache static files for 7 days (since i dont expect openwebui to change css jpg and other image files etc. that often

and this belongs inside the main location area and will ensure cache gets invalidated after 12hrs

# Add strict cache control headers
expires 12h;
add_header Cache-Control "public, no-cache, must-revalidate, proxy-revalidate, max-age=43200";
add_header Pragma "no-cache";

Feel it would be worth setting no-cache on files served from the /static directory.
Strangely it looks like fastapi's mount doesn't support this without some middleware or subclassing StaticFiles.
