I recently bought a shop built on OC 1.5.6.4 and it works quite well. But I have a concern: the man I bought it from appears to be an a-hole, and when I bought the shop, I also received the domain and the main login for that is my own, and I'm the only one who knows it... BUT! The MySQL and FTP logins are still the same as before, and I have to change it for my own safety...
But when I do that in the control panel from the hosting company, the shop fails. Where do I tell the shop that I have changed the password ? I have read a lot, but I can't figure it out. Somebody talks about c-panel and so, but I think there must be an easy way to do it. I can login to MySQL - but can't find anything saying something about changing password...
I would really appreciate your help
