wrong query expression when clicking onto 'older' within a card category
When visiting /cards/channelname/?cat=categoryname and scrolling to the button, as expected the button 'older' appears.
When clicking on that button, one is forwarded to /cards/channelname/?cat=categoryname?page=2
(no older cards within that category are shown), while it should be /cards/channelname/?cat=categoryname&page=2
(older cards shown).
Issue was not there before, it appeared about 5 months ago I guess.
I want to mention that on /cards/channelname/?cat=categoryname?page=2 when clicking again onto the 'older' button, instead of increasing the page number to 3, another query ?page=2 is added, summing up as /cards/channelname/?cat=categoryname?page=2?page2
All this doesn't happen when visiting the cards page without a ?cat=categoryname query.
The combination operator for several queries should be &
instead of another ?
