That’s alright. I am just glad that you found the cause of the problem and are able to work on a solution. Take as long as you need to finish it.
Update:
I kept digging through the podpress_stats table just to be absolultely certain I didn’t miss anything, and I actually did end up finding rows with a media name containing URL encoded parentheses. I suppose this would explain why these rows are also showing up in the podpress_statcounts table. This issue seems to be occurring over many different languages, browsers, and operating systems according to the stats stored in that table.
