Hi, I recently updated Cornerstone on a website from 2019. I’m now having multiple issues as follows:
- Cornerstone is showing “The preview could not load due to iframe…”
- The website is displaying completely different to the way it was designed. Was full width, had a Rev Slider, various sections and a form at the base - none of which are showing up now.
- “There has been a critical error” is stated on the webpage (see attached)
Can you tell how to get the site back?
