When you try to edit posts or pages while using the Massive Add-ons for WPBakery Page Builder plugin, you may receive an error 404 – page not found.

If you encounter this issue, you can take the following steps:

1. Examine the server error log. A server resource shortage or by server settings can cause this failure. In that case, you’d need to contact your hosting provider to make the necessary changes.

2. Add this rule to your .htaccess file:

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

If the problem persists after you have followed the steps outlined above, please contact us at su*****@se******.com.
