Having Same Problem
I am having the same problem, but I first noticed it because the events do not show up in list view. (Which would make sense because I am guessing that's what Event Manager is using.) Past events do, if you don't use any list view options and just have it show the current month's events. I can only get Monthly repeats to show, not daily, weekly, or yearly.
I am using 6.2.12. I don't know on the php or mysql, as I am not the programmer that set it up -- or a programmer at all for that matter!. I just have enough logic/programming skills to get by and usually make it do what I want it to do. Glad to see I'm not the only one with the problem, as I thought I was going crazy last night trying to make it work. Is this fixed in 6.3.13? I hadn't seen anyone else with the problem, so I didn't know if you were aware of it.
Thanks in advance for any help you can give!
