[Valentina R]

3 people reported this in the past 5 days. 2 same examples, one a bit different.

2 examples with the same error in edit-order and no appointment in backend:

And the other user has no error but shows like this (it’s an appointable product - in order notes you can see the first note with the appointment ID):

Another report from 6 months ago (v 4.15.0).

[Valentina R]

All users have shared their plugin list and they have no plugin in common. 3 out of 4 have the Yoast SEO plugin, but not the fourth (the one that has been having issues for the past 6 months).

They have different server setups and use different payment methods.

Any chance this happens because of server overload or something similar? Since we have 4 reported cases, it’s not a light bug to just ignore. But we have no info on how to reproduce it because it happens randomly.

One of the users had this happen again yesterday.

It keeps happening. here is an error log: https://bookingwp.com/wp-content/uploads/2023/09/php_errors.txt

for this order:

another report here.

[Željan Topić]

Most users are probably using outdated custom templates they copied inside their theme as errors cannot be traced to current code lines. Added additional check for gCal server load with 4.18.0

This has happened again to a customer that had this issue in the past.

He recently switched to using HPOS but I was not able to reproduce it with the same settings. He shared the error log - it had errors at the time of the order creation: https://bookingwp.com/forums/topic/new-order-for-appointable-product-but-no-appointment-included/#post-849962
