This was some how being caused by a conflict with WP Lightbox 2 which is an abandoned plugin. Once I stripped that from the site, the error went away and all is well! The only other (unrelated) issue I had was my repeater template had self closing icon tags like:
<i class="tt-icon" />
When rendered, they were not being closed correctly and caused formatting issues.Easy fix but didn’t seem to be an issues in the last version.
<i class="tt-icon"></i>
Thanks for the support and for the great plugin!
Thanks for following up! I have been rolling the staging instance back and forth to test some different configurations so that probably caused the 503 as it can take a couple minutes each time.
I’m going to try disabling all other plugins and re-enable them one at a time to see if I can get more info and will post results.
