Hi judi45,

Did you try uploading class-wp-widget-factory.php this file ??

web hosting provider that I use, make improvements server on the 29th of January 2016 then there is a problem on my site, please help me?

Fatal error: Class ‘WP_Widget_Meta’ not found in /home/xxxxxxxx/public_html/wp-includes/class-wp-widget-factory.php on line 43

I’m also having this problem. Host is using an old version of MySQL. It causes havoc with migration / DB imports. Old site is dead (Joomla) now the new site is dead. Joy!

PHP Fatal error: Class ‘WP_Widget_Meta’ not found

aaahhh … finally compelled me to open a new site
