I installed this great https://www.ads-software.com/extend/plugins/maxab/ plugin, but it does not work with multisite. I have tracked the problem down to total visitors. For some reason it does not register users visit to database and therefore $experiment->original_visitors and other variations is always 0. Any chance you could point me to the right direction? ??
Thanks

Try posting in the plugin’s dedicated forum. And please don’t post hundreds of lines of code here. Use a pastebin.

The thing is that no one reads the dedicated forum and author is busy with other projects. It has to be a simple error in the code and that’s why i was hoping that people with multisite experience can spot the problem in the code. Next time i’ll use pastebin, sorry ??
