so i pressed on " update automaticly " after 5 min i opened the website
and i found first fatal error in Plugin " the social links " u deleted it
then a new error shown " wp-statistics " i didnt delete it beacuse its improtant so i red in forums + google and changed the name of the file so

a new error came :

Fatal error: Class 'WP_Widget' not found in /home/husonline/public_html/wp-content/plugins/wp-user-avatar/includes/class-wp-user-avatar-widget.php on line 9

so i renamed the Plugins file in file manager " Cpanel " to Plugins.disabled
and created a new folder named Plugins " empty folder "
and then a new error came ...

Hi, and welcome to Trac.

Trac is meant for tracking features and bugs in the core WordPress component, this sounds like a single incident, we ask that support requests such as this be directed to our forums at

To get things started though, this sounds like a potentially failed update, please try the Manual Update approach from, and if the problem persists create a post on the forums as mentioned above.

You will not lose any content from performing a manual upgrade, but we still recommend making backups when possible.

You will have to create a new topic on the support forums, there is no link between them and this issue tracked.
