Whenever we try to upload an image, we get this error: Warning: escapeshellarg() has been disabled for security reasons in /*****/*****/public_html/*****/includes/GlobalFunctions.php on line 1473 and the image doesn't upload. In place of where the image should appear, the following is there instead: Error creating thumbnail: Unable to run external programs in safe mode. How do we fix this please?
