When adding memcache directive to config.php site crashes

Nextcloud version _(eg, 12.0.6) (but has been an issue way before)
Operating system and version _(CentOS7)
Apache or nginx version _(Apache/2.4.6 (CentOS))
PHP version _(70w)

The issue you are facing:
When I add the line ‘memcache.local’ => ‘\OC\Memcache\APCu’, to /var/www/html/nextcloud/config/config.php my website will no longer load. I cant find anything really difinative that relates in the log. I have installed php70w-pecl-apcu and php70w-pecl-memcached and ive ran #pecl install memcache and done about 50million other things ive found online and im at a loss at this point.

Is this the first time you’ve seen this error? No:

Steps to replicate it:

  1. Install nextcloud
  2. follow directions at https://docs.nextcloud.com/server/12/admin_manual/configuration_server/caching_configuration.html

Thank you for your help

Do you have the php-memcached package installed? Did you look into the apache error log?

https://jackbox.zone/index.php/s/7dwiWsnhxifkS9x has a copy of the files if you want to look but I didnt see anything in them to give it away. Sorry that link might have been down.

[root@jackbox httpd]# rpm -qa | grep memcache
