At http://gullmars.se I am running the Contempt theme with custom CSS to display a slightly wider page than the standard theme and slightly tweaked image frames.
Since the Infinite Scroll feature was added to my blog I've had several problems:
With Infinite Scroll setting on: The only way to see all my posts is to set the "Blog pages show at most" setting to an absurd number like 1000. If I set it to a more normal number I only get the ajax loading to work a couple of times and then it looks like my blog history ends after some 20 posts. This behaviour occurs in both IE9 and Chrome 19.
With Infinite Scroll setting off: The "load more posts" button doesn't appear more than a couple of times in Chrome. In IE9 however the "load more posts" button shows up as intended.
Also some of my two column galleries show up as one column galleries when they are loaded through the ajax loading function (even those that were already on screen displayed correctly before the load). This happens both in IE9 and Chrome.
Could my custom CSS be interfering with the gallery columns? Before the infinite scroll feature was added I never saw problems like these.
I've cleared my cache(s) and cookies and tried the site on a couple of different computers. In Chrome I've also tried without any extensions (adblock, keep optouts etc) loaded, but no change.
Hope you can help!
