Hello Heidi,
Thanks for getting in touch!
I checked your system information – thanks for sharing – and I do not see Events Calendar PRO in it. You need to have PRO installed and activated in order to have recurring events.
Might be that something went amiss during the last update or it was removed by mistake.
You can download a recent version from your account here.
If you need help with the manual update, this article is your place to go.
Let me know if that helps.
Cheers,
Andras
