I updated to Cornerstone 4.8 and it killed our Contact Form 7 plugin. We can no longer receive forms. Instead, the user gets an error message that says: There was an error trying to send your message. Please try again later.
I need to know if reverting back to the last working version of Cornerstone will restore this issue for us.
I have a previous version from a backup. Version 4.7. Will deleting the current version of Cornerstone and reloading 4.7 do anything bad to our site?
You can look at the form here: https://www.preferredpump.com/test
