Dear Jan
Sorry to say so, but I personally think you make your live a bit easy by just refering to the server. We installed about 15 Jommla Webpages on this provider and everything works fine for years. It is only your new update, which does not want to produce pdf files....
So I think, as we all payed for this extension, you should provide a bit more of a solution than just hand to problem over to the sever or us.
Again, sorry to say so, but if you want so sell your extension, it must work well not just...
I switch back to invoice 1.0 which is, regarded to its well function options, still the best version so far. Again, this is my opinion.
Regards
Klaus
