Fatal error: Cannot redeclare class Mobile_Detect

Hello TaHuC,

First of all, please ensure that you have right installed your theme with the latest version of it via FTP because this is the surest method in this regard. Also, if you are using some untested plugins, please try to disable all of these and install only the plugins that come bundled with the theme packet and rule out any conflicting plugins. If the problem is still there, please try to make a new clean install from scratch via FTP and install only the required plugins and check the results.

Hope this helps and let us know how it goes!

Thanks for the message!
