Moving WordPress to a subdirectory breaks the plugin

[pyronaur]

From https://wordpress.org/support/topic/moving-wp-site-url-to-root-breaks-plugin :

I installed the Photography plugin and all was working well. My WP site is installed in a sub-folder i.e. http://domain.com/wp1/, but I want to adjust my site URL to point to the parent level i.e. http://domain.com I know that this is done in the WP general settings page. When I do this, it breaks the Photography Plugin. I have uninstalled the plugin, changed the site settings, and then reinstalled the plugin, but that did not resolve. If I revert the site settings back, then the plugin works again.
I figured that there is a setting somewhere, either in the database or a config file where a file path needs to be updated. Can you point me to what needs to be adjusted to allow the plugin to work after I adjust my site settings?

I'm also working with a subdomain, but the plugin does work (apart from an other bug).

I copied the entire Wordpress site from domain.com to beta.domain.com. Plugin works on both sites
