Limited Support
Our team is currently on holiday, so support will be limited during this period. Response times may be slower than usual, and some inquiries may be delayed.
We appreciate your patience and understanding, and we’ll resume our usual support by the end of August.
Like I said, the avatars were working before but all of a sudden some users started getting those little question marks and as far as I know, we haven't changed any avatar settings ☹️
I guess after deactivating other plugins and WP User Avatar you've forgotten to click on [Delete all caches] button in Dashboard > Forums > Dashboard admin page.
Also I need to see that page on screenshot to debug the image source URL. The members page is closed, please open it temporary or send some admin login details to support[at]gvectors.com email address.
