Then in the left column (filter) click on "Themes" and "Landscapes"
You arrive at the same url, but the read more is not working.
I am not sure which extension (CF Filters for Virtuemart), Regularlabs or the VP template is causing the problem.
Could you give me a hint?
I think there is a JS error, but I cannot find the cause.
That content is being loaded via ajax (javascript).
This means that:
1) the Tabs & Accordions scripts and styles are not being loaded on the page (as there are no tabs/accordions found on the initial page). You would have to load them manually via the template or some other way.
2) The Tabs & Accordions scripts are not initialized when that content is loaded. You would need to add a javascript command to init them when that filter thing loads content. Not sure if that filter extensions allows that.
