This issue was caused by his site being on a shared server and the server’s global php session folder was set to “/tmp”, which he did not have access to. His access started in a client folder like “/homepages//htdocs”. So his app didn’t have permissions to the global session folder and was reporting a lack of disk space because it couldn’t write files there.

The fix was one line of code that changed the php session folder to somewhere within his reach in the file system, given his file permissions:

ini_set(“session.save_path”, “/homepages//tmp”);

This needs to be placed in the php code at a point before any sessions are being created. Change the above path to match your path on the server and create a tmp folder there to serve as the new location for sessions. Make sure the file permissions allow php full read/write/modify/delete access to the new location. That immediately fixed our problem.

It’s not a one off as the three different servers I using are all (bless them) RIP.

Just an update for you all, and it’s amazing at how apologetic front line tech support can be.
