Store stopped working

Hello, We recently discovered that a store that was created some time ago, and honestly probably not receiving too much traffic, which is why we probably didn't discover this until now, has an error when you go to the store page and any relevant buying pages within it and does not allow you to purchase anything. Here is the initial error that is at the top to the page when you go to one of the products pages:
Warning: session_start() [function.session-start]: open(/home/content/35/2405535/tmp/sess_r586o0grmneag6sj24hn1nh484, O_RDWR) failed: No such file or directory (2) in /home/content/35/2405535/html/saraimica/WA_eCart/WA_eCart_Definition_PHP.php on line 465

I have attached all relevant files, please let us know if we can provide anything further to understand where the problem may be coming from. Thanks!

It looks like a server configuration issue you would have to bring up with your hosting provider.

I would guess it is an issue with the session_save_path set in the php.ini file and that the folder specified either has the wrong permissions or doesn't exist in that location.

Is there a chance that it is something else? The reason I'm asking is because this happened with another site of ours recently as well and when I brought it to the attention of GoDaddy, and escalated it multiple times, I was told it was not an issue on their end. Is there any chance that there is any issue with outdated eCart tools that we are using? We are getting some errors when we try to open Server Behaviors files, Cart object, etc mostly pertaining to JavaScript errors??? Not trying to take it off GoDaddy, we are just stuck and we are not getting anywhere with GoDaddy. Thanks so much!

It looks like the error is thrown every time session_start() is called. Each error file and line has that code on it.

That is not a line of code that has any setup needed. It simply starts a session, so it can't be an issue with that line of code itself.

The second two errors are caused by the first one, so the first error is the relevant one.

Warning: session_start() [function.session-start]: open(/home/content/35/2405535/tmp/sess_r586o0grmneag6sj24hn1nh484, O_RDWR) failed: No such file or directory (2) in /home/content/35/2405535/html/saraimica/WA_eCart/WA_eCart_Definition_PHP.php on line 465

So you can see the error is in the line of code: session_start()

There is definitely nothing wrong with that file itself.

The error says that there is no such file or directory, and the file or directory it is looking for is:
/home/content/35/2405535/tmp/sess_r586o0grmneag6sj24hn1nh484

Now, when a session is started it is supposed to create a file unique to that session in the folder specified in the session_save_path setting from the php.ini file. Usually that is a temporary file in some sub-directory on your server. You can see that the missing file is in a directory named /tmp/

The file it creates doesn't have an extension and is named with a unique key matching the session id for the logged in use and starts with sess_.

That also perfectly matches the missing file referenced in the error. That tells me that the session file was not created properly and could not be found.

Now, am I 100% sure? No. But I'm making a very educated guess and I'd be willing to bet on it.
