HI,
We are having an issue with the page builder preview and receiving the “The preview could not load due to the iframe response being incomplete…” error. The preview error only happens when pages are ‘published’ or ‘private published’, and preview functionality will return if pages are set and saved to ‘draft.’ Also note that there is an exception to this with our homepage, with this page functioning as expected regardless of the pushing status.
We have already gone through and disabled all plugins, as well as our child theme to see if the issue could be coming from there, however, the issue persists in all cases. We have tried to identify any common components or global blocks that could be contributing to this across the pages that are giving us the errors but are unable to find anything. We have also come across other threads where some people are having similar issues however the solutions were not clear.
Please advise on what the next steps will be how this can be resolved. Thanks for your time.
Cheers.
