In some cases you may get error 404 – page not found when you try to edit posts or pages and you have Massive Addons for WPBakery Page Builder plugin activated.
If you face this problem, you can take the following steps:
1. Check the server error log. Reasons for this failure might be a server resource shortage or server settings. In that case you would need to contact your hosting provider to make the appropriate settings changes.
2. Add this rule to your .htaccess file:
<IfModule mod_substitute.c> SubstituteMaxLineLength 10M </IfModule>
If you still encounter the problem after you have taken the above steps, please contact us at firstname.lastname@example.org.
