XF 2.3 Issues after upgrading to xf 2.3

[Faust]

Hi. I have upgraded one of my forum. And now have started to received multiple issues on my dashboard:

php version: 8.4
CloudFlare set

First isue:

Symfony\Component\Mailer\Exception\TransportException: Email to email.com from no-reply@email.com failed: Process failed with exit code -1: src/vendor/symfony/mailer/Transport/Smtp/Stream/ProcessStream.php:74

Second issue:

ErrorException: IndexNow error: [429] We're sorry, but you have sent too many requests to us recently. src/XF/Error.php:81


#0 src/XF.php(266): XF\Error->logError('IndexNow error:...', false)
#1 src/XF/IndexNow/Api.php(88): XF::logError('IndexNow error:...')
#2 src/XF/IndexNow/Api.php(34): XF\IndexNow\Api->request('/?key=TnbcjhN7W...', Array, 'IndexNow error:...')
#3 src/XF/Job/ContentIndexNow.php(84): XF\IndexNow\Api->index('https://dji-pil...')
#4 src/XF/Job/Manager.php(275): XF\Job\ContentIndexNow->run(7.69356)
#5 src/XF/Job/Manager.php(205): XF\Job\Manager->runJobInternal(Array, 7.69356)
#6 src/XF/Job/Manager.php(89): XF\Job\Manager->runJobEntry(Array, 7.69356)
#7 job.php(46): XF\Job\Manager->runQueue(false, 8)
#8 {main}

Any advice why I do get these issues? Thanks

The first is an email sending problem; check SMTP.

Is the theme you're using designed for 2.3?

I use @Russ style XenBase.

The first is an email sending problem; check SMTP.

Mine is set php email, so by the look of it I need to set the STMP on this case.
