Hi,

I have several issues with my forum, with the same kind of error in logs.

1. One topic on my forum can’t load anymore. I get this message (it’s in french) :

 ![image](https://global.discourse-cdn.com/meta/original/4X/4/0/5/40515871315fc7080e2abb3df9c7c754b971d8f3.png)

It used to work just fine until now, the only thing I did is to reduce the size for the images in the settings, and then change it back. Could it be the reason of this error? How can I fix it?

Here is the log when someone tries to access the topic:

1. Users are unable to change their avatar. I use [Discourse SSO](https://meta.discourse.org/t/13045?silent=true) with Drupal, and the option **discourse\_connect\_overrides\_avatar** is checked. But even after log out/log in, the displayed avatar doesn’t change, even though I can see the new url on the admin page of the user.

I get this log:

This was an error a while back ([Issue in uploading media files](https://meta.discourse.org/t/issue-in-uploading-media-files/289037) and [Bugs appear while i try to upload files (520, 422 Eror)](https://meta.discourse.org/t/bugs-appear-while-i-try-to-upload-files-520-422-eror/289291)). Just to check, have you updated your Discourse recently? If you could provide the version link from your dashboard that’d be really helpful as well.

It looks like if you upgrade you’ll pick up the fix for this issue. 🥳

No worries. 🙂 Though let us know if it doesn’t fix things.

Hi,

After the update, the broken topic is back (yay), but the avatars are still not synced, even though the url of the picture is correct on the admin page.  
I tried to log out/log in, refresh the cache of the web browser, it doesn’t work.

No, I don’t, I only have some unrelated deprecation notices.

The url of the new avatar is fetched, but the old one is not replaced.

Maybe I should mark this topic as solved and open a new one, since the issues don’t seem to be related ?

There was a change to another setting that may possibly be connected. The `uploaded avatars allowed groups` site setting was recently changed to allow `groups` instead of a `min trust levels` style setting.

Could you check that and see what group you have in there, and also check whether you’ve changed their visibility at all from their groups page:

> [@Users can no longer customize profile pictures](https://meta.discourse.org/t/users-can-no-longer-customize-profile-pictures/290335/13):

> I would like to ask you to check one more setting. I am interested in the visibility of Trust Level 0 group.

I changed this settings, and after a log out/log in and a refresh of the browser cache, the avatar has changed.

Thanks a lot ! :meow_heart:
