Entering the WordPress update to 5.6, there are a number of problems that arise in clients using the WordPress CMS, usually the ones that are complained of:
The editor menu does not appear
WPBakery doesn’t come out of the tool
Messy look
Blank white front page
Wp-admin menu messed up
When the mouse is over to a menu in WordPress admin, the dropdown menu will not appear
Some pages on the admin menu, blank do not partially exit the menu, or the sub menu tab menu cannot be clicked
Cannot log in, even though there is no change in password / user access
