Can someone please help with this please?

[andy_b_1502]

Is it something to do with this:

 

Please verify that the current setting of session.save_path is correct (/home/users/web/b109/ipg.removalspacecom/cgi-bin/tmp) in Unknown on line 0

 

How would i fully check this is correct? cpanel somewhere?

Do you have access to your php.ini

[batwimp]

From php.net:

 

If while testing locally on your Windows machine you get many warnigns like:

 

Warning: session_start()... failed: No such file or directory

Warning: session_start()...: Cannot send session cache limiter - headers already sent

etc.

 

you need to configure properly the session.save_path in your php.ini file.

 

Set session.save_path to an existing folder on your PC.

For example: session.save_path="C:\Temp";

[andy_b_1502]

Yes, i have access to my php.ini on my cpanel.

 

What do i need to change what to??

[batwimp]

You need to make sure that the line in your php.ini file:

 

session.save_path = "C:\Temp"

 

actually gives a path name of an existing directory. Also make sure there isn't a semicolon before it, as this would comment it out. The default installation of php.ini shouldn't be commented out, though there are some other lines that look similar that should be commented out. (i.e. skip the ones that say session.save_path = "N; /path"  and  session.save_path = "N;MODE; /path" etc.

[batwimp]

It looks like yours is commented out. Remove the semicolon and change the path to something like C:\Temp or another folder that exists on your machine.

[andy_b_1502]

That was just a defualt .ini uploaded....

 

mines this:

 

session.save_path = /home/users/web/b109/ipg.removalspacecom/cgi-bin/tmp

 

 

on my server, this should in theory work shouldnt it, meaning that the problem is elswhere? is that true??

[Jessica]

Where did you come up with that path? Or are you saying that was the default?

Your server is looking in "/hermes/bosweb25a/b109/ipg.removalspacecom/", not /home/ etc.

[batwimp]

Apparently not. The server can't write to it, or you wouldn't be receiving the error. Try changing it to something more generic that exists, and see if it works.

[andy_b_1502]

On my control panel i locate my php.ini file....

 

 

In the session section, session.save_path = home/temp etc...

 

here is the whole section:

if i create a new folder on my file manager called 'sessions' and the path to that is: /sessions

 

and i change the session.save_path to:

 

session.save_path = /sessions

 

 

Will it work without it crashing/messing up? just checking before i try it?

 

 

[batwimp]

No idea to know until you try! But put the full path in there. C:\whatever\sessions

[Jessica]

No idea to know until you try! But put the full path in there. C:\whatever\sessions

Stop assuming he's on a windows machine!

[batwimp]

You're right! Sorry, I thought he said he was. But I never got confirmation.

[andy_b_1502]

right okay so ive changed it to:

 

session.save_path = "removalspacecom.ipagemysql.com/sessions"

 

I get this:

Any ideas guys?

[Jessica]

The error is telling you where it's attempting to find the file. I don't even know where you got the removalspace stuff from?

[andy_b_1502]

on the server?

[andy_b_1502]

And why is it attempting to find a file that doesnt exist? i thought session start() started a session?
