That was exactly what I checked before. My user is already on the “admin” group on that box. I even changed my group to another group and back to “administrators” to see if that could work, but nothing changed.
I don’t know how to upload a screenshot in this forum, I can’t seem to find an icon or link to do that. How can I do it?
Also, I tried to create a new admin user, but I still have the same issue, can’t upload images, change pluin settings, etc.
Thank you very much for your quick answers and explanations!
