I'm trying to install ajaxplorer at a shared hosting in my home folder. When I navigate to the main page, I get an error:

is_writable(): open_basedir restriction in effect. 
    File(/var/lib/php5) is not within the allowed path(s): 

What might be the cause? How could I fix it?

There is php 5.3.3 installed, apache 2.2.16. I use ajaxplorer 4.0.4.


The problem is caused by this code part:

$tmpDir = session_save_path();
$this->testedParams["Session Save Path"] = $tmpDir;
if($tmpDir != ""){
   $this->testedParams["Session Save Path Writeable"] = is_writable($tmpDir);

Error appears in the last line, but I enclosed the context.

What script/line generated the error? Can you paste the relevant snippets? – Jay Jun 9 '12 at 23:43
Open basedir is a PHP security configuration parameter. Ask you hosting provider to change it, install in a location include in the open_basedir allowed paths. I assume 'other-path' points to your vhost dir? – Halfgaar Jun 10 '12 at 6:10
@Jay Shah: I don't know, where exactly the problem ocures I'm just trying to install a downloaded application. – mrzasa Jun 12 '12 at 21:53
@Halfgaar: I added other paths. Provider won't change paths (btw. adding there /var/php5 seems to be not the best idea). I cannot install it in any other place. – mrzasa Jun 12 '12 at 21:55
@Halfgaar: I added code snippet what cause the error. – mrzasa Jun 12 '12 at 22:19

Can you try adding this to the top of the file:


If that works, you'll need to put it in a file that will be included by all other files for good measure (such as a configuration one where you specify your database details).

Alternatively, you can try adding a .htaccess flag or custom PHP.ini (former if you are using suPHP, latter if you are not). But let's try this first and see what happens.


Finally I had to put:

define("AJXP_TMP_DIR", AJXP_INSTALL_PATH."/tmp"); 

in the conf/bootstrap_context.php file and it helped.

Finally I had to put: session_save_path(AJXP_INSTALL_PATH."/tmp"); define("AJXP_TMP_DIR", PATH_TO_AJAXP_INSTALL."/tmp"); in the conf/bootstrap_context.php file. Still this answer was helpful, so I', accepting it. Thanks! – mrzasa Jun 13 '12 at 19:32
tha second line was of course: define("AJXP_TMP_DIR", AJXP_INSTALL_PATH."/tmp"); – mrzasa Jun 13 '12 at 21:26
