Good evening Barak and welcome back!
Thank you for reaching out to us.
We are sorry to hear about the struggles you have been experimenting after the latest update.
I would love to help you with this topic.
Bases on the system information you have submitted, I have several recommendations (which should help):
- You are still using PHP 5.3.x . If possible I would recommend upgrading to at least 5.4+ . The reason for this is that there are several odd behaviours that have been reported with earlier versions of PHP. In fact, WordPress even recommends 5.6+
- You are still using Event Rocket. That plugin, although great, has not been updated in quite a while and is known to break several things as of the Events Calendar 4+, I would recommend deactivating this plugin
- We will soon be sunsetting Woo Tickets. This plugin has been replaced with Event Tickets Plus. For now, it should still work, but in case the other tricks do not help, I would recommend temporarily deactivating the plugin to see if that helps.
Let me know how that goes.
Best regards,
Geoff B.
