For the suggestions, please have a look at the "Search" page if the catalog suggest plugin is placed there and it doesn't display something like "Invalid value". Then check the catalog filter plugin on your "List" page. Edit the plugin and check if it correctly links to the "Search" page.
Is there anything else not working?
I checked the content of the search-page. It shows Catalog list JSON as plugin.
The listpage->catalog filter points to the Page Search as searchfilter and "Counts" for Page with product counts.
That looks ok to me.
In the field for category levels is no entry. I tried a "5", but didn´t find anything when choosing for "demo" on the Page list.
Exists there any tutorial explaining the structur of the shop and where to edit which content or do you rely on self explanation only?
Indeed, there is something not working having to do with realurl: Clicking an article on the Page List, the Page Detail is displayed correctly with an url like this:
http://grabsteinportal.de/grabsteinshop ... t-Auswahl/
But when calling for items of the feature "zuletzt angesehen" under the above url, I´m still getting a fault.
The called url looks like this:
showing the page-id Nr.71 instead of the realurl and coming with the error message, as known:
Page Not Found
Reason: Segment "71" was not a keyword for a postVarSet as expected on page with id=1.
The page is online, so that you might check the address on your own.
