Good evening Cheryl and welcome back!
Thank you for reaching out to us.
We are sorry to hear about the next event listings being really odd in Pro.
I would love to help you with this topic.
Aside from a PHP max execution time of zero (I would recommend a setting of 300), I do not see anything obviously wrong in your system info.
Can you tell me if this worked well prior to a recent event ? And if so, would you know what triggered this odd behaviour ? (upgrade, change of something on your site, etc…).
Could you also 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.
Hang in there as we try to reproduce this.
Best regards,
Geoff B.
