Can't save changes in Sections anymore

Hi there,

Are there any errors in the "Console" tab of developer tools (right click + inspect) when trying to save?

Let me know :)

Hi Guys,
I have the same problem. What's the solution?
Regards Dirk

Here is a screenshot of my Google console.

Not sure what meta-box-loader is, but it seems to be getting a 403 error which is a permissions error from your server. Perhaps it's a plugin you're using causing the conflict?

For your information:
The cause is the firewall in the Wordpress Toolkit

Glad you got it sorted :)
