Hi

I've updated the version of PHP running

which version?

on my Mac OSX server and the new version includes mcrypt which I didn't have before. Since then I've not been able to log in.

There appears to be a problem with the length of the initialization vector being handed to the mcrypt function, the interesting thing being that the length is changing each time: 11, 18, 9, 12.

The error logs show:

Grateful for any advice!

quick workaround maybe to change program/include/rcmail.php lin 993 to $iv =8; but I'm not sure what long term effect this will have.
