Hi, I found the solution. Sometimes it can occur that you enter an expires on date and that people are not able to register before that date. I don’t know why this issue occured and sometimes it didn’t, but I found the solution.
The issue was in the date comparison. In the file plugins/wp-simplemeetingconfirmation/simplemeetingconfirmation.php you have to change
date('d/m/Y') <= date($SMC_expireson))
to
strtotime(date('d/m/Y')) <= strtotime(date($SMC_expireson))
Be careful, it occurs two times in the code.
Good luck!
