Forum/Portal Login Sync Bug

vot

First of all try to uninstall all the non-default plugins!

After that try yet another idea:

Ask your friends to try to login and jump to Portal/Forum.
If they have no problems - so the problem is on your local PC.
If they have the same problem - so the problem is placed at your site.
