Error 404 when trying to edit in WPBakery Page Builder plugin

If Massive Addons for WPBakery Page Builder plugin is activated and you are getting error 404 – page not found, when trying to edit the posts/pages:

1. Check the server error log. It might be server resource shortage or server settings.

2. Add this rule to your .htaccess file:

<IfModule mod_substitute.c>
SubstituteMaxLineLength 10M
</IfModule>
