I paid quiet a while ago and i can't seem to post messages in the forum. All i get is a invaild session message
Email them and give them the date you paid ➡
Invalid session error messages are nothing to do with your user account, or even if you are a member of not. These problems are almost always related to your web browser type, its security settings, or if you are using some kind of proxy server.
What web browser are you using?
