I get this when I try to go to the profile page
Fatal error: Call to undefined method UserModel::GetMeta() in /home4/hsafight/public_html/animeveo/forums/plugins/MyProfile/default.php on line 71
perhaps it is version related, what version of vanilla and theme are you using. I don't see the problem in 126.96.36.199.
I may not provide the completed solution you might desire, but I do try to provide honest suggestions to help you solve your issue.
I'm using the timely theme and I'm using version 2.17 because the 2.18 kept giving me the "bonk" error whe n changed themes
maybe the method is not defined in 2.0.17 and the plugin needs to have a 2.0.18.x requirement, just a thought.
Your version is not supported.
grep is your friend.
