Hi Daniel!
I have this problem too and I really need your help. I use infinite scroll and limited the number of posts to 12 in settings/reading. Correct me if im wrong but this is the way to limit the page showing 12 at a time right?
Now, none of the pagniation options work for my home page. Have a look at http://ozgur.se and you will see that the 12 first posts are the ones that get loaded again when reaching the bottom, over and over again. I tried changing between the different settings but nothing works. I also tried adding the strip of code above in my index.php but that didn´t do the trick either.
However, pagniation works fine on the blog page http://ozgur.se/blogg.
Could you please help me get this to work on the home page as well.
Thanks in advance!
(ps: You seem to have big issues with onedesigns.com in general (500 error). Everything stops working every other minute and I had to wait and reload over and over again)
