That is correct. The message disappears when debugging is disabled.
It is hard to understand, though, why debugging result in this, and only this, message.

Yes, that release fixed it.
Thank you!

To clarify, I have created a template for see the details of an event. On the event itself, I select that template. There is nothing in the event record to override that template.

Thank you for this update. I look forward to testing it once it is in production and fully documented. Unfortunately, I am not in a position to be a beta tester of this update.

I double-checked the logs: the errors occurred 6 minutes before the upgrade to 2.2.63. So I suppose all is well. Thanks. Sorry for the false alarm.

Yes!!!
Before ver. 2 of MooWoodle you could do a sale without even having an account on the WP site! For this reason, I never upgraded beyond ver 1.3, which is the last version that had a reasonable workflow (IMHO).

So you’re saying that there is an SMTP authentication problem, the mail must be coming from a plugin that does not use the WP mail functionality, but rather is configured to send directly to some SMTP node. Is that right?

Thank you, Mirko, for this contribution. In fact, I already use exactly that snippet.

The problem, though, is to understand which action is triggered when Stripe sends back the message the the SEPA payment has been made, which normally occurs some time well after the order is placed. Is it indeed woocommerce_payment_complete ???

When you use Stripe’s test environment, the whole transaction happens immediately, so it is impossible to distinguish between placing the order and confirming the payment. I suppose a network sniffer could yield that information, but I am not equipped with that. And I do not want to test this in a production environment.

Thank you, Igor, for your message. Unfortunately, it is not pertinent to my issue, which is NOT a question of physical vs. digital (it is neither). It is a question of different payment methods.

Thank you for that, but my question is which action or filter should be used to handle the message from stripe that payment was received.

Yes, that is correct. But I do not intend to add yet another plugin to do something that must be simple enough, if only the relevant filters or actions were documented somewhere.

Screen shots sent.

Yes, I have set up a service category including all services.
However, I have now tried the Time Slot Auto Lock function, without the expected result.

I selected the service category in which all services are found.
I selected a date range from today until 31 Dec. 2023, using the calendar. (2021-12-29 – 2023-12-31)
Note that I have never yet configured anything for 2023 before this operation
I set the time slot as 11:00 to 15:00.
I removed all days of the week except Monday.
I clicked on Start.
After a little while the following message was returned:

Total locked: 0

I would have expected a lot of time slots to be locked.

I did not realize that a single service could be in multiple categories. So what you suggest above does indeed what I would like to do.
THanks.

I have tried some settings with Schedule Tools and now I cannot reproduce the problem. So unless there is something else you can add, we might as well close this.
