Good evening Nahum,
Thank you for the link,
Could you please send me a copy of the latest version of your WordPress theme / child theme via a link to a .zip file link (stored Dropbox or Google Drive) so that I can run some tests on my end ? I recommend a private reply for that purpose.
Please ensure you are using the latest files as found on your actual website.
This way I will get access to any updates or customizations you might have made.
Additionally, I would highly recommend upgrading to the latest version of our plugins (after a database backup).
That would be:
- the Events Calendar 4.5.1
- the Events Calendar Pro 4.4.7
Could you also try temporarily reverting back to a default WordPress theme such as twenty-sixteen to see if the issue disappears ?
Hang in there!
Geoff B.
