By comparing the both installations I found a very big difference in All in One SEO. Under the working test.sportguide you don't have some fields under "benutzerdefinierte Inhaltstypen" = userdefined contentypes, there you have just media. Under the sportguide website that causes problems you have some new fields for Toolset where the title-format is defined: I attache 2 pictures of it. Could that be the mistake? Why are there more fileds and what should I write into or shalI delete them? Have a look on the pictures.
I found the solution: Under "extended settings" "create automatic descriptions" was used/checked. You have to turn off the automatic description and then your map is working! I hope you can use this for other users!
