XF 1.5 403 Forbidden when attempting to edit some templates.

When I edit templates, 80% of the time this happens:

I have no idea what the heck is happening, and I would really like to get my forums going (and templates edited appropriately).
Any/all help is appreciated.

This is likely a false positive caused by a mod_security rule on the server.

You (or your host) may need to adjust the mod_security config or at least disable it temporarily to see if that seems to resolve the issue.
