I'm working on a magento community 1.8.0.1 shop. During the development of an extension, I noticed that other extensions with cron job configured weren't running when I hit cron.php.
I tried to troubleshoot the problem through magento files, but I got stuck in the /lib/Varien/Profiler.php
file.
I tried to disable my current development (via configuration > system > advanced, and via xml file), checked php and magento error logs before going on debug through magento files, now i'm getting stuck, I don't know where to start to troubleshoot this issue. The cron worked like a charm for a long time, I just don't know why and when it stopped working.
