Well, VC is shortcode builder. All theme modules can work without VC. So, you can create draft page, then, configure modules with visual composer, then switch to classic view – text view and copy shortcode code. Delete all VC shortcodes from code (
[vc_column], etc. All of them start from
[vc_...]). Then, you can use such shortcodes without enabled visual composer.
Go to Theme option General option . You can find toggle for this option. Note, that some scripts are not working on frontend (some post carousel, sliders), but you can control them.
We added many ready helper classes which you can use. Check them here
Tips: If you want to insert ads block inside posts string, you can do it by inserting 2 posts string, but second string must have offset option equal count of posts in first string. For example, first string has 5 posts and second – 5 posts and offset 5. So between these string you can insert ads block or any other block.
