Hi – I noticed with the last theme update, it created a bit of a ripple effect on the display of static blocks in the main menu when using Visual Composer ‘Row Settings’.
See settings for Row Stretch, default, stretch row, stretch row and content, etc.
I’ve had to revert back to the previous theme update in my life environment but you can replicate this issue by creating a static block in mega menu and try and plug in columns, etc. and you’ll see what I mean.
Take a look at my ‘Private Content’
