Good evening Leila and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the fact that your website still requires a login to add an event in spite of the Allow Anonymous Submissions setting being used.
I would love to help you with this topic.
As a first troubleshooting step, could you please provide us with your complete system information in a private reply using the instructions found in the following link?

Secondly, could you please send me a screen capture of your Events -> Settings -> Community settings so that I can try to run some tests on my end ?
Best regards,
Geoff B.
