I configured $wgSMTP in LocalSettings.php with a set of credentials and IP addresses that worked in past versions of MediaWiki but now, with version 1.27.1, I get an HTTP 500 error when I try to generate a new password and an e-mail is not sent.
E-mail used to work with a PEAR folder in the wiki's root folder as described at http://syrkos.com/blog/2013/04/12/manual-install-of-pear-mail-in-mediawiki/
I read that version 1.27 no longer requires a separate PEAR install so I removed the folder and commented out $pearPath = .... and ini_set (step 8 in the linked article).
What can I do to fix the problem?
