Guys I need a CMS with a good forum and member picture gallery. I used postnuke for a while, dropped that, currently use MDPro. My goal is to set up a series of websites with different CMS's and themes - that way they all look a little different. There should not be a lot of news poste on the front page, maybe some downloads and a web links section, along with a good forum and easy to use picture gallery for members.
Cookies problem tends to deals with miss configuration. If you have dragonfly setup wrong. IE site is at mydomain\dragonfy and and you have your cookies setup as:
mydomain and cookies directory is /
Then yes it will tell you that you have cookies problem.
Since I noticed that your main site is running MDPro instead of DragonflyCMS, then I would assume that you have setup DragonflyCMS in a subdirectory. Please check your setting before jumping in conclusion that DragonflyCMS doesnt work.
