Bandwidth Issues

How do I discover which page really screwed up my monthly bandwidth allowance?

These past few weeks I have had to shut down my website for maintenance. I have not yet discovered which page leached all my bandwidth, but I am hoping I will find out!

Google Analytics, WordPress and Piwik statistics have not yielded any useful information, as they only count pages. The statistics provided by my provider Transip.nl however have shown interesting information. Somehow, on May 7 there was an increase for the stylesheet of my chosen theme. I guess one of the Ajax scripts running for this theme never stopped running, but I do not have enough knowledge to verify if this was the actual problem. I have since deleted the theme and let’s hope for the best!
