My site crashed / there are PHP/JS errors.
First of all, please make sure that all of the plugins and Blaszok are in the newest version. Please also remember to update Wordpress. If the problem occurred please disable all plugins not bundled with the theme and check again. In worst case scenario you need to contact with your hosting provider and make sure that your server is running on at least PHP 5.4+ and has more than 96M memory.
