My straight forward php social networking script (not phpfox or any other one like that) allows members to enter profile information like myspace, and also include CSS to make their backgrouns different. A good amount of people write daily asking what trick they have to do in order to get a background image on their profile. Some people say that they'll enter code, save, and go back and it's gone as if they never entered it. I believe this is happening because of some of our security measures.
Security is very important, but we should be able to modify in a way that will allow members to not have trouble inputting CSS in their profile, and or links to images, etc. Any experts have an idea on what needs to be done?
