After the update, we noticed that the blog categories were no longer displayed in the sidebar. When we go into the Widgets section in WordPress, we can see the individual widgets but cannot manage them. When we call up the live preview, the following error appears:
Fatal error: Uncaught Error: Call to undefined function mysql_error() in /home/artwin.ch/wwwbeta/wp-content/plugins/revslider/inc_php/db.class.php:29 Stack trace: #0 /home/artwin.ch/wwwbeta/wp-content/plugins/revslider/inc_php/db.class.php(124): UniteDBRev->checkForErrors(‘fetch’) #1 /home/artwin.ch/wwwbeta/wp-content/plugins/revslider/inc_php/revslider_slider.class.php(720): UniteDBRev->fetch(‘wp_revslider_sl…’, ”, ‘id’) #2 /home/artwin.ch/wwwbeta/wp-content/plugins/revslider/inc_php/revslider_slider.class.php(756): RevSlider->getArrSliders() #3 /home/artwin.ch/wwwbeta/wp-content/plugins/revslider/inc_php/revslider_widget.class.php(19): RevSlider->getArrSlidersShort() #4 /home/artwin.ch/wwwbeta/wp-includes/class-wp-widget.php(519): RevSlider_Widget->form(Array) #5 /home/artwin.ch/wwwbeta/wp-admin/includes/widgets.php(274): WP_Widget->form_callback(Array) #6 /home/artwin.ch/wwwbeta/wp-includes/class-wp-customize-widgets.php(1050): wp_widget_control(Array, Array) #7 /home/artwin.ch/wwwbeta/wp-includes/class-wp-customize in /home/artwin.ch/wwwbeta/wp-content/plugins/revslider/inc_php/db.class.php on line 29
