Two things need to be fixed on my Joomla web page.
1. Log in button stop working ( see attachment 1) needs to be fix and work without any conflict with other 'log in' button and extensions.
2. Very often ( not all the time / see attachment 2) after log in users see information "invalid token" and white screen. This thing needs to be fixed as well.
I need someone experienced with this kind of issues.
