WP Bakery Visual Composer don't function properly

Could be related to the content hooks of WordPress. Maybe I’m using the same hook as your theme, but we have to do the changes in the correct order.

You can fiddle around with the setting that determines the priority of my plugin’s changes to the content. For this, add the following code to you wp-config.php

define( 'FOOTBALLPOOL_CONTENT_FILTER_PRIORITY', 30 );

The number defines the priority and default it’s 30, so you can try a lower value (e.g. 10) and a higher value (e.g. 50).

thanks a lot for your great support!
Your solution had resolved my problem (I left the value of 30)!

Only a problem remain: the toolbars icons become like “ball” icon of your plugin, instead of default icons… Could I try to change the value to 50 or 10 to resolve or it’s a completely different problem?

Please see the Screenshot.

Looks like a completely different problem. And it’s a strange one.
I use the standard WP functions to add a toplevel admin item and I set the icon to the football icon using CSS. But this rule in the admin.css file is pretty specific, so can’t really think of a reason why this is going wrong.

Hi, thanks a lot for you answer and support!
Pherhaps, could be the child theme?
Whatever this isn’t a real problem, the plugin seems is working, so thanks again for your precious time.
