Hi,
Thought I would let you guys know my website primarily uses the Slider Revolution plugin. I should note the homepage did not use cornerstone at all and was edited only with slider revolution.
When updating Cornerstone from 3.5.5 to 4.0.1 it gave me an error similar to:
/home/(profile)public_html/(*website url).com/wp-content/plugins/cornerstone/includes/componets/class-shortcode-finder.php on line 206 through line 276.
It gave this error for every line and it showed across the home page.
Rolled back cornerstone and website is good now. Hope this can help out somehow! Sorry no images.
