I did some more searching and I found that downgrading Mailpoet to 3.7.1 is the fix – the conflict does indeed come in Mailpoet 3.7.2.

All better now.

Hope this helps someone!

I had the same issue – Error 500 – but only when accessing the Admin side of my site – after updating to WP 4.9.6.

Disabling Ultimate Member -or- disabling Mailpoet fixed the issue.

However, my site is running Mailpoet 3.7.2, so apparently that either broke the fix they put in 3.7.1, or there is a new issue / conflict between UM and MP 3.

The PHP Error is:

[Sat May 19 11:18:50.406635 2018] [cgi:error] [pid 93167] [client 75.165.178.185:59889] AH01215: PHP Fatal error: Call to undefined function get_home_path() in /<redacted>/wp-admin/includes/misc.php on line 204: /usr/local/cpanel/cgi-sys/ea-php56, referer: <Redacted>/wp-admin/plugins.php?plugin_status=all&paged=1&s

I had the same issue – I traced it to a mod_security rule:

comodo_apache 226473 COMODO WAF: CSRF vulnerability in the MailPoet Newsletters WordPress plugin before 2.6.11 (CVE-2014-3907)

This rule causes requests to your MailPoet admin panel to fail.

I disabled this rule in the Mod Security Tools section of my WHM control panel and things are working again.

If you don’t know about Mod Security or COMODO, it may be something your web host has configured and you need to ask them to disable this rule.

Good luck,
Rowland

Having the same problem – displayname is showing in the member directory for users added before installing ultimate member, but not for users added after installing it.

Another vote for this one – I’m stuck with NextGen unless users can upload photos – thanks for considering it!
