OK so I cleared the error log and updated to 2.1.6

There is now only 1 type of error occurring, and it's a different one:

Asa you can see it's all the same error, with only one line different each time.
Of all 11 errors so far, all of those in read are unique.
All are from "Yesterday at 11:05 AM" it remains to be sen if anioterh pops up troday.
I note the error type is: cron

Could this be related to a cron job copying forum files/database to an external backup?

@GL700Wing - you set up some cron jobs for me at one stage - does this make any sense?

I didn't upgrade any of the sites just yet. That may be a different story. I'll let you know if there are any problems.

I have a few of our updated themes on my main site and both 2.1.5 and 2.1.6 updates went OK Mick with no issues all the themes seem to be working just fine

2.1.5/6 implemented a fix to the mail queue that...  slows things down.

There have been more & more mail transports that drop or error out on various mail send conditions.  Historically, SMF could just connect to the SMTP server & hand it off, and the mail transport would relay the message if & when it could.  It was now in the mail transport's queue, not SMF's mail queue.  Newer mail transports are either dropping or returning errors, in real-time, causing emails to get stuck in the SMF queue.  When this happens, as an example, invalid recipients could cause a huge logjam in the SMF mail queue.

So...   A fix was made to handle such errors & warnings, and to reattempt delivery over the next few hours.

The bottom line is that you should see fewer/zero stuck-in-the-queue or dropped emails.

At the same time, it will not process the queue immediately.  There will be a waiting period.  Most folks aren't too happy about this.  I suspect there will be a speed-it-up fix at some point.

@lurkalot sorry just saw this - ok done.

Notifications are broken again, the emails seem to be stuck in the queue. I'm unable to force send them I click send now and nothing happens.
The email test works, it seems to be a bug in 2.1.6

...AND I missed that there is a PHP 8.4!

I'm curious Steve, how many of your themes will need updating for SMF 2.1.6  We noticed a lot of custom themes are getting several test failed during these last updates.

Regarding TinyPortal

At the moment: Highest supported PHP version (tested): 8.3.1

Ah! I didn't know that about TP. Thanks.

I've updated to 2.1.6, the test site was running it for a while no issues.
I haven't upgrade PHP we are still on 8.3, that is the latest version that will run with TinyPortal
