Hi,
I am seeing an error when trying to install CMSB:
Warning: session_start(): open(/tmp/sess_780464de0539451a806538a189e9f74c, O_RDWR) failed: Permission denied (13) in /home/muscle/public_html/cms/lib/init.php on line 620 Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/muscle/public_html/cms/lib/init.php:620) in /home/muscle/public_html/cms/lib/init.php on line 620 Warning: Cannot modify header information - headers already sent by (output started at /home/muscle/public_html/cms/lib/init.php:620) in /home/muscle/public_html/cms/lib/menus/header.php on line 4

I spoke to my web hosting support who deleted all the files from /tmp yesterday which got rid of the error. I tried to visit the page again today and the error is back.

Here's what my web hosting support had to say:
From what I am seeing it is a coding error that is causing this, information is being sent before the start of the session and due to this the code is failing to execute. I can delete the temporary file for you again, but you may want to check with CMS builder's support if it continues to occur.
Something in the code is generating a temporary session file, and it is being called to at the start of the session for what you are trying to complete, according to the error it appears that it is cms/lib/init.php that has made the file and then tries to make it again when the session_start() function in that site is called, so this causes a conflict.

I would like to resolve this issue incase it causes more problems in the future. I am now concerned that it could be causing the below caching issue on the same server:

Thanks for your help!

Hi,

Is this a new installation of the latest version of CMS Builder (3.06) or are you copying/moving an existing installation?

Does the /tmp/ directory have full permissions?

Let me know. Thanks!

This is a new installation of CMSB 3.04. I currently have CMSB installed on the server in a different account, and am now trying to install another copy into a separate account on the same server. The link he refers to below is the first install of CMSB I mentioned. Here's what my hosting support said:

I can confirm that the TMP folder has the correct permissions set. Looking into that error it looks like it is an issue with the headers being sent out before they can be modified.

The file /home/strong/public_html/cms/lib/menus/header.php is sending out the headers but the other files need to modify them, but because they are already sent it is not able to.

Here is some background info on the error:
