Forbidden 403 on test send or save as draft (SOLVED.)

I just ran into this issue whereby emails with certain images in (not all, seemed random) resulted in a 403 Access to this resource on the server is denied! page.

I hadn’t changed anything myself that would affect this, and had been working flawlessly for years, so I contacted my host company (Krystal) and asked them. They asked me to disable ModSecurity for the domain in my cPanel. I did, ran the same tests and this time it sent and saved the draft.

The hosts then seemed to change something behind the scenes and asked me to re-enable the ModSecurity switch, and all was working again.

Posting so that this might help others with similar issues.

Many thanks for the info, as you say, it may help someone else.:grinning:
