Hi,
thanks for your post, and sorry for the trouble.
That 403 response code means “Forbidden”, and is coming from your server.
It appears that some security software or firewall on the server is raising this. My guess is that this software is configured too strictly and doesn’t like something about the data that is part of the “Save Changes” request that the browser is sending to WordPress/TablePress on the server (it could be the structure, the size, or even the content of the data).
It then (wrongly) thinks that a hacking attack is going on and blocks this request before it even reaches WordPress or TablePress.
Therefore, this is nothing that I can influence in TablePress, so that you would need to contact your server admin or your webhosting company’s support team about this.
They will need to relax the configuration of that security or firewall software, so that it allows these requests to pass.
They should be able to find out more about what rules need to be adjusted in the server’s error log files.
Regards,
Tobias
