Hello,
I just took the time to register to these forums to let those who are having this problem know how I solved it.
Many people may be experiencing this issue because of a problem with php_sessions.
My webhost, Ipower, recently migrated to a new hosting platform. In so doing, some of the changes have caused certain php powered applications to stop working. I believe this also affects a few other hosts such as Powweb and Ipowerweb, and any Ipower reseller hosts that just upgraded to vdeck 3.0.
With respect to this problem, the following is the solution I used.
I created a folder called "phpsessions" outside of my public_html folder. That is to say, if the following is the path to my public_html folder:
/home/users/web/blah/ipw.domain/public_html
then I created:
/home/users/web/blah/ipw.domain/phpsessions/
Next, open up "main.inc.php"
Look for:
//Start the session
session_start();
Replace with:
//Start the session ini_set("session.save_path","/home/users/web/blah/ipw.domain/phpsessions/");
session_start();
Hopefully this solution will help others experiencing the same problem. I believe you can also fix this problem by editing the php.ini file on your server, however since I am running multiple php application I thought it best to use this solution so as to not break anything else in the process of fixing this.
