I installed this plugin (http://www.s2software.it/en/download/joomla-image-resize-cache) and I have this error, this error remains too after creating images/cache folder, on my server are available these: Imagick Shell Execute, JImage (GD) but no one want to work ...
And in System Information every folder, and file is writable, except configuraion.php
Here is a step by step solution that I have found: and it's working very well:
$obd = ini_get('open_basedir');
Comment out that line with // at the beginning so it becomes://$obd = ini_get('open_basedir');
Another solution without any Joomla's core file hacking:
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:
"Absolute Path(you've just found)"/tmp
php_value open_basedir NULL
