A programmer from Scriptlance installed a [login to view URL] on my server, it allowed me to retrieve my clients personal information after them sending it on a secure website. It has been a little while back now and it used to work smoothly. I have been wondering lately why I never received any information from prospective clients. I filled out the mortgage application form myself and it gives me the following error message "Can't connect to MySQL server on '[login to view URL]' (60)" Can someone help me to fix this. Check the website in question: [login to view URL]
