Hi!
There are limitations to that feature, that if some other features are enabled, it automatically uses the redirection method. It should display a warning message if so, but I accidentally made a change to that warning script, it was only recently discovered.
Basically the load more feature will not work if:
– The results grouping is enabled
– ..or using the polaroid layout
– ..or when using the isotopic layout and this option is set to “Don’t show that result”.
Usually it is either case 1 or case 3. It should display a warning message when enabling these options together, but unfortunately it does not due to that recently discovered bug.
