I have zero issues with DOL 7. I have not touched or altered anything. It's hosted on simple install of Scientific Linux. We have put it threw the gears for 3 months before deciding to use it with our online game currently 47% threw development.

In fact I am so impressed with DOL 7 I have been recommending it to others. (Something I have never done with Dolphin before) When hosting on windows servers you will have nuthing but issues. As Windows servers are made for dummies and do not have the see more same robust functions as Linux.

If your having issues or bugs or what not. You need to look at your server config or host the site yourself on your own server. Sadly if you can't figure out it works and keeps blaming user error on the DOL team you probably lack the skills necessary to set up and maintain a Linux server.
I have been doing this work with web and programming code for 15 years. I am wrong about alot... but not this

DOL 7 Works. If it don't for you, your doing something wrong OR your host is not as compatible as you might think.
