Hello. We cannot upload images. Says processing, but nothing happens and there’s a load of console errors:
Have updated to latest version, no change.
Same in Edge, Firefox and Chrome, on Windows 11.
Any suggestions?
There was a similar error reported recently that may have been tracked to the Pavilion Events plugin, if you have that on your site too? Disabling it seemed to fix it in the short term:
We do, thanks. I’ll look at disabling it.
Yes, you have to remove it from the app.yml and rebuild.
Previous event data won’t be lost. It’s still in the database, just inaccessible while the plugin isn’t in use.
Fixed now, by removing the events plugin from app.yml and rebuilding. Thanks all.
To remove it entirely you would edit it out of your app.yml, but in some cases simply disabling it in the settings is enough. It’s normally the first setting on the settings page. 
I’m not sure which @jerry0 did in this case though.
I also removed from app.yml
In my use case I cannot disable or turn off events as we actually require it (as a need.)
I am now reverting back to 2.9.0.beta8 vs 2.9.0.beta9, tested on other environments, 2.9.0.beta8 and events plugin together allow image uploads through the Composer WYSIWYG again.
