Hi Luis,
So sorry you’re having this problem, but I’m happy to help!
Recurring events is a function of TEC PRO, so while it’s a silly question, I must ask, have you associated your license key with your plugin? Without this step, the recurring function may not work. (Read more on that here)
That aside, because I’m unable to replicate this issue on my testing server, this seems that it may be a theme or plugin conflict. Though you may have already done this, would you please work through the steps here to test for a conflict? This will help me be able to better assist you. 🙂
Let me know about all of that and we’ll work this out from there. 🙂
Best,
Shelby 🙂
