On the site, the errors shown below are appearing on the bottom of the home page, and also appear when I try and complete a SagePay test payment.

Doing a bit of digging, it appears it may be something to do with a firewall blocking permission, but not sure. Can anyone confirm this, and also, does Expression Engine need to connect to a port?

It seems it can't write to the folder because of incorrect permissions on the folder.

Possibly change the location of where the sessions files are saved (e.g. in a tmp_sessions folder) and change the location in Plesk.

given you're using CartThrob and SagePay - we had a similar problem back in December. Have a look at extload.php inside themes/third_party/cartthrob/lib and update as required.

That certainly fixed our issue.

We have checked the extload.php file and it seems fine, what pieces of information did you have to update when you were having this problem? –  Tom Pickering Sep 2 '13 at 12:36
    
we had to set EE_absolute_server_url and that should be the server path and not actually the url –  Steven Grant Sep 2 '13 at 14:04
