Version 4.4 update – Fatal error: Class 'WP_Widget' not found

Hello everyone.. Try this method.. hope it helps..

for safe update/upgrade..

backup your database first..
then backup wp-content folder, wp-config.php and .htacces file..

now you can copy all content of the new/updated/fresh wordpress files&folder..
and replace all the content of your old wordpress files..

so for example:

if your current wordpress files are inside “mysite” folder
..root/public_html/mysite/(copy in here)

next copy : wp-content folder, wp-config.php and .htaccess that you just backedup

and paste it inside …root/public_html/mysite/(copy in here)..
and it should replaced the files..

open you site in web browser and you should see (update button)

lastly click on update/upgrade button..

and it should work..

=======
if you already having that problem… you can do the same..

thanks..
