I have some problems with your extension.
Tested with no difference with Member Avatars & Status v1.5 and v2.1 (from Github).
Tested with differents styles, including untouched ProSilver.
I have the extension Board Portal v2.2.0-b1.
- On some forums from the Index, avatars are shown, but on some, it's the default avatar, including for a given member (i.e. Administrateur)
- When I'm on the portal, some avatars are garguantuans and others don't even appear...
By the way, in subforums, everything seems normal...
Does someone has any clue about this, please?
