Your instructions on how to be able to access templates that time out helped. I was able to recover the new template that timed out by this process.
We still don't know what is causing this. It looks like you are saying it is caused by me adding a condition statement on every template that checks if the body is empty, which is untrue. Definately not for the template I just had issues with.
For now - with the templates which was having issues that is reported with this ticket, replacing the conditiional block that checked post body (post content) with custom shortcode fixed the issue. This is not from me but our next level support shared this and I shared with you and that also helps to fix the issue.
If you remember - I also help you with the templates where you used Toolset Form block and replaced that with shortcode block having Toolset form shortcode.
