This bug occurs when searching/sorting under the "Players" tab, specifically when accessing the site via an iPhone or iPad Safari browser. With "weekly stats" selected, the players cannot be sorted by clicking on any of the column headers unless you go to the second page. For some reason they work then but not on the first page.
Obviously I've figured out the workaround is to go to the second page and click the column header but figured someone would want to know so that it can be fixed to work as intended.
Please link me to the page you're having trouble with. It's working fine here and sorting OK.
Well, it's working now on iPad but not iPhone. Here's the link:
