Hi there
On a site today, every page that had a contact form 7 using the Form Integration element broke. The pages all returned error 500s and on the odd time they loaded, it showed either just the content and no styling or all the JS on the page (header dropdowns, animations) didn’t work.
I tried deactviating all plugins, clearing caches etc etc and when I checked error logs I found:
/home/sites/15a/1/13ad2bbe94/public_html/wp-content/themes/pro/cornerstone/includes/classes/elements/class-element-definition.php(593): x_element_render_form_integration(Array)
I then went and switched the contact forms to just using the shortcode in a content area and it worked a treat. No idea why the form integration was causing it and obviously I’ve fixed it now so I can’t show it but thought I’d flag it in case it happened to anyone else.
