Hello @rozindzakwan,
Thanks for getting in touch with us.
I suspect there’s a conflict that’s causing the issue here. It would be good to test for conflicts. Could you follow the following steps?
- Deactivate all other plugins except for The Events Calendar Plugins.
- Switching to the Default theme.
Please read the Testing for Conflicts article before doing anything.
To be safe, we’d recommend conducting tests and updates on a Staging Server. Also, please keep a working backup of your website.
Once done and the problem persists, please share a screenshot of what you see and the error messages.
I hope that helps. I am excited to hear back from you.
