configured request variable limit exceeded

Has anyone come across this error before? I googled and it is common enough, but the solution seems elusive.

I'm getting it when I try and limit module access to certain groups. (kernel/admin/index.php?page=modules)

This is with the most recent beta of R2 and PHP5.2 (hardened, built by SuSE.) The fact that the hardeing was done by suse makes the only known solution (remove hardening) a little complicated.

I think this may be your suhosin settings in php.ini
Try adding:

to your php.ini and see if that fixes it for you.

Yep, that did the trick.

Of course, you proably won't be surprised to learn that there was no suhosin section in the php.ini file. (:cry:)

If there had been I might just have noticed it!

Anyway, thanks.
