I'm having an odd problem when I try to run the security check in csf. It gets down to the point of "Check shell limits" and then I get a popup box notifying me that the site has sent an incorrect Message Authentication Code. No other area in WHM, or any other website has ever thrown this message up in my direction before, so I am not exactly sure what is going on. I am currently running CSF v2.50, with WHM 10.8.0 & cPanel 10.9.0-C117
The error message only shows up if I use firefox (version 2.) With internet explorer 7 it just stops at the same point with nothing informing me of a problem.
Any suggestions?
edit:
I'll also note that this account is on a VPS machine, I manage 2 of them and I am having no issues at all with CSF on the other.
