Question

I am trying to install a new extension in Joomla,But I am getting this error Message: "JFolder::create: Path not in open_basedir paths Unable to create destination"

What is the solution?

Answer 1

I have test another solution thanks to the user @farahmand and it's worked very well and I decided to provide a step by step guide for the solution

Solution One:

First find the exact absolute path to your tmp folder by using this trick:

Create a PHP file in your website root,for example path.php

Place this snippet of code in the file and hit the save button

<?php
$path = getcwd();
echo "Your Absolute Path is: ";
echo $path;
?>

Navigate to yourdomain.com/path.php in your browser

From now on:

1. Login to your Joomla Administartor panel.
2. Go to Global Configuration
3. Click no the "Server" tab
4. Change the path to the "Absolute Path(you've just found)"/tmp

5. Insert this line of code in your .htaccess file: php_value open_basedir NULL

   this solution has been worked very well for me,and it's doesn't need any Joomla's core file hacking.

Here is another step by step guide for the second solution:

1. Login to Joomla Administartor panel.
2. Go to Global Configuration
3. Click "Server"
4. Change the path from /public_html/tmp to "tmp"
5. Login to control Panel(CPanel)
6. Open File Manager
7. Open Folder "libraries"
8. Open Folder "joomla"
9. Open Folder "filesystem"
10. Right Click on "folder.php" and click Edit.
11. Look for the line, (search = obd): $obd = ini_get('open_basedir'); Comment out that line with // at the beginning so it becomes://$obd = ini_get('open_basedir');
12. Save and Close.

I have tested @johanpw's solution and it's working very well too,but sometimes you can't change the Joomla configuration from Joomla Backend,so you must change the configuration.php parameters directly using your control panel or a FTP account.

Answer 2

Another solution suggested at the Joomla forum is to enable the FTP layer.

The FTP layer can be enabled from System -> Global Configuration -> Server tab -> FTP Settings. Add FTP details (host, username and password) for a user with access to your server.

I'm not able to test it myself because I can't reproduce the error, but apparently by enabling FTP, Joomla is able to overcome certain server limitations.
