This is only happening on a single page…
Will not save any content updates.
Just started around 2 months ago.
Templates are all gone too (entire site).
This is what is displayed:
NOTHING!
Green bar does not finish but success message still shows.
Very frustrating…
Hi There,
You could try testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
Kindly also make sure that the theme and the plugins are all up to date.
If the issue persists, would you mind providing us with login credentials so we can take a closer look? Please provide following information:
Set it as Secure Note
All the best!
Looks like it is saving now… but still an empty template area… not plugin related 
Hi @scojo88,
In this case, please share us the details we asked above so we could further check.
Don’t forget to set it in secure note.
Thanks.
