Hello @schentrupsoftware
Thank you for the update, glad to know that you were able to further narrow down the issue.
I was able to narrow it down the “Gutenburg” plugin. When I disabled it, the form showed up in the editor.
I tested the scenario on my lab site which is a vanilla WordPress installation and checked with 2024 theme & the Speil Theme (which your site seems to be using) but could not replicate both issues. Forminator Block on Gutenberg works fine. Please refer to the screen recording. https://monosnap.com/file/OWmjmnB9uq9hFu6rqbGO8J8jikcOLf
This means that the issue you notice on the Edit page while using Gutenberg is limited to your site – which probably could be an issue with the template/content. I can understand you already have Gutenberg disabled as you don’t use it and currently the site is working as it should, however, if you wish to further narrow down the issue with Gutenberg you can try creating a test page & a test post on your site without any content and simply add the Forminator form and see if that works.
Further, please allow me to clarify, the issue you noticed on the front end could be a common cache issue and enabling the form to load via AJAX and disabling cache on the form page seems to resolve that. I also noticed that you have Cloudflare enabled on the site – I would recommend you also purge all the Cloudflare cache and any server cache and check if the form issue on Gutenberg on the WP Admin backend is resolved too.
Hope this helps.
Kind Regards,
Saurabh
