I believe this is a bug that was supposed to have been fixed in RC 11, but in looking at the archive today, it appears RC 11 doesn't include some of the corrections that should have been included. I'm going to dig into this further.
In the mean time, if you open the file located in your /plugins/system/ directory called "jwhmcs-sysmlang.php", at about line 101 you'll see a line that was commented out (that shouldn't have been). Take the double slashes off the front of it and see if that fixes the issue you are having. If not, let me know what your SEO settings are in the Global Configuration and I'll try to replicate.
I am currently using RC 5 on my site. I have tried logging in so I can download the latest build but I am going round in circles. I can login ok into the site but when I try going to the Client Area it asks me to login again. I login but it keeps going back to the WHMCS login form. Do you know whats going on?
