Hi Cornwolf, I just want to add, although the WP plugin is free, and as a developer I have access to the source – it has been a bit of a pulling hair out exercise.
Unfortunately this is what you get from a “free” solution.
But again I have to stress, this is by no means a polished product, and if you do not have the technical skills to fix the poor implementation, then this solution is going to lose you real money, when things on your site don’t work.
Yeah, tried a few too, none actually seem to work so far…
Alright, I found the provided solution to be impossible to implement, difficult to understand, and essentially some kind of work around hack.
So I decided to do the job properly, and having now tested it, I wrote a blog post on how to really do it:
