Hello,
I accidentally updated my production website to the latest version of X (v6.5.6) and immediately had a problem. Any post with a video embedded no longer displayed the video… but showed an iframe of a missing page on my own site. Nothing would fix this… so I reverted to v6.5.2 (I had it handy) and got things working again.
I set up a local test environment using the backup of the live site I’d made prior to upgrading the X Theme and tried again. Same issue.
Here’s an image showing what it looks like:
Any thoughts? If not… be aware that this could be a bug in v6.5.6
Thanks!
