I've found another bug. Quite annoying
When user log in on frontpage and go to activities details, there is a BACK button to the activities list, but it doesn't work:( it opens a blank new tab in browser. Could you plz look at it? lucascomputer.eu the login and pass U should have:)
most likely you have a conflicting plugin.
the button is rendered using standard Joomla functions, so there must be a different plugin that injects the target="_blank" attribute, causing you to open a new tab.
