I am running photopost classifieds 5.1 and a member contacted me letting me know (in a less than happy manner) that she received over 20 emails this morning telling her that her ad was expiring. She has 1 ad running. I know there is a newer version out there now but upgrading to see if that fixes it is not an option at this time with what is on my plate. What could be causing this? Can I simply disable the emails all together? My classifieds are integrated with vbulletin.
