Ok, some further info.
Snippet with above code is called "get_tags"
I have one chunk on homepage which calls
[[!getResourcesTag? &tvFilters=`tags==%[[!get_tags]]%`...
this works fine and outputs the menutitle from the snippet.
However, another chunk calls
[[!getResources? &tvFilters=`tags==%[[!get_tags]]%`...
but the snippet doesnt output anything here?
what could be causing the problem? I used to just use
instead of get_tags snippet before, all this worked ok, however I had to tweak the output further hence the use of snippet instead of just a placeholder call.
