Sorry about that, please try with the updated information in the hidden content.
Once again so you have all the info here:
The issue is with saving a module. Here is a direct link to a test module, add anything and then save it and you will see everything is lost: https://www.americanbrotherhood.com/J4/administrator/index.php?option=com_modules&view=module&layout=edit&id=130&client_id=
Additionally the site is now not using the Custom Style under Presets that I set up to change the colors on the site. This worked before you looked at the site so I am not sure what is going on now. I went into Helix Ultimate and I can see them fine, and re-saved in case it was that but still the site is not using those custom colors and settings there.
I was getting this error below after you looked at my site, I got past by disabling the Plugin: Content - SP Page Builder. But I think this should be looked at too.
Call to undefined method SppagebuilderHelper::onIntegrationPrepareContent() when I go to the Home page https://www.americanbrotherhood.com/J4/index.php This I got past by disabling the Plugin: Content - SP Page Builder
