I have multiple local installations of WordPress and want to have a single Must Use Plugins directory for all my local sites.
Is there anything I can add to wp-config for instance that will let me have a single folder which can be used for all my sites? Or perhaps another approach?
Yes, you can set the
WPMU_PLUGIN_DIR constant in the config file of each of the sites (and
WPMU_PLUGIN_URL for the url).
By default it is defined as:
WP_CONTENT_DIR . '/mu-plugins'
Try to create a symbolic link within wp-content for each site:
ln -s /root/mu-plugins mu-plugins
