Urgent - Need fix for Joomla permissions problem

Closed - This job posting has been filled and work has been completed.

Job Description

Previously had DTRegister Plugin working fine, but recently something changed (permissions!) and the response file from a payment using Paypal (ie http://www.cre8conference.org/mel/components/com_dtregister/success.php?return=123&Itemid=157&task=notification) does not execute and redirects to root of site.

Cannot figure out what is causing this - seems like .htaccess, but this seems OK!

Need someone to get into the site and fix this problem urgently, so people can register for our conference.

In the process, want to find a reliable developer we can call upon on a regular basis.

Skills: paypal
