How can I change the localization of a plugin? (Without installing loko translate, etc.)? I translated the strings using the "edit" program, and created .mo and .po files - uploaded them to a separate folder under the name of the plugin, in /languages/plugins/advanced-quiz/ - it does not work. I tried placing the files inside the /languages/plugins/... folder (without creating a separate folder) - that doesn’t work either
