Good evening Dalia and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the calendar not being accessible on your website. Yikes!
I would love to help you with this topic.
Before we begin, I am noticing that your system information displays the following value
max_execution_time = 0
This is known to cause several issues (not just with our plugins). I would recommend looking into that. Perhaps with the help of your web host. A more common value for that parameter is 300.
Secondly, I would recommend heading over to Events -> Settings -> Display.
Try out a few different values for Events Template and see if that changes the result you are getting when clicking on the “where is my calendar” link.
Finally, please make sure that you do not have a “real page” with the /events/ slug.
Our plugin needs exclusivity over that slug, even though it is not using a “real page”.
Let me know how that goes.
Best regards,
Geoff B.
