First of all, thank you for your responses. They gave me clues and directions where to look further and explore the topic. I have spent so much time on these issues that it is hard to imagine, returning to the point where I won’t change links for filtered Loops – the topic is beyond me.
Ultimately, archive pages won’t use query loop filters, so they have a default template and I only added a filter to change pages for archives like /page/2 etc. And some custom Query Loops will remain as they are.
The plus side, however, is that I have infiltrated quite a few cool places from databases, file hierarchy to various functions ??
