Hi @SomethingWonderful,
It mostly happens due to the broken HTML which is been added within the content. I would suggest you check by deleting the section one by one till the issue is fixed, and the last one you have deleted before the fix is the actual issue. If that does not resolve the issue, there might be some different reason behind your reason, I would like to suggest troubleshoot the following common issue to help us to recognize the reason.
1.Plugin Conflict
2.Theme Update related issue
3.Child Theme Related issue ** if you have activated it
4.CSS/JS Customization
If none of this helps, please create a separate thread and provide login credentials for your site in a secure note to examine it further, including:
– WordPress Site URL & Login URL
– WordPress Admin username/password
