Yesterday i decided to update PHP. I used EasyApache to do this. I didn't change any setting except the version of PHP. Now every site that uses session_start() triggers open_basedir. we use the open_basedir option so that users can't get into other users folders and files. I tested to make sure the session_start was the problem and it was. I installed a demo site and crated the index.php file with the following code. PHP: <?php session_start(); ?> And sure enough i get the open_basedir error. I Googled the error and read others are having this issue too. From what i can gather my real /tmp directory is in /var/tmp I tried adding this to the include_path and also to open_basedir but still have the error. Any suggestions on how to fix this or a better way to build Apache+PHP and have the security feature where other users can not get into files and folders of other users on the server? Any help would be great. Thank You!
