Ok, so I went to Events > Extensions where I can see a list of Extensions and notice that (I assume the ones I use) are now marked as “Not Activated”...Mailchimp
Guest Bookings
I then went to the Plugins section of my WordPress site and saw two banner headings…
The plugin eventprime-EventPrime-Mailchimp-Integration/eventprime-mailchimp-integration.php has been deactivated due to an error: Plugin file does not exist.
The plugin eventprime-guest-booking/eventprime-guest-booking.php has been deactivated due to an error: Plugin file does not exist.
I then download the latest version of both extensions - Mailchimp and Guest Bookings.
Incidentally, it isn’t clear how to do this. I visited https://theeventprime.com/checkout/order-history/ and then clicked “View Order Details” and then scrolled down to find the products in question and clicking the links which triggered a download.
However, when I tried to upload the zip file for either on the plugins page I got this message…
This plugin is already installed.
I then went back to the Plugins page, where it appears that v4 of the Mailchimp and Guest Bookings plugins were already present(?) but just deactivated. I activated both of them.
And then when I returned to the Events > Settings > Extensions section I could now see my two Extensions listed again. And when I clicked to investigate them I could see my settings had been retained. So that was feeling more hopeful.
But the problem remains - I still see a blank Booking page when trying to checkout tickets for an Event.
Hmmm… a further update.
I’ve encountered a blank Booking page before with EventPrime and recalled it was related to payment.
So I went to Events > Payments where PayPal was listed as the Payment Processor with the Status toggle set to “On” but the Default toggle set to “Off”.
Since PayPal is the only Payment Processor listed, but there wasn’t a default specified, I could see why the Event code was having a problem.
So I changed the Default toggle to “On”… and the bookings facility sprang into life again. I’ve now been able to make a test booking.
Note: I did also used to use Stripe as a Payment Processor previously (but I don’t believe it was the default).
Anyway, I take it back… Version 4 did NOT break my site! (Admins feel free to rename this thread)
