[Solved] changedata.php download instead of page update...

[shawn_a]

Your host is redirecting those pages because it is detecting xss injection probably.

Have you checked the contents of these downloads to see what they say ? Is it actual source code or just a 404 or something page ?

Have you disabled all plugins?
Have you checked error logs, gs and host ?

Either way , bad host config, probably a blind redirect instead of a 302 or 404.

I'd suspect MOD_SEC
