After starting my wordpress maintenance - updating plugins and wordpress version - I lost AAM menu in my admin menu. Besides that I lost also any evidence that AAM plugin is still working in WP. I cant see it in plugin list, nor as deactivated plugin. Though the plugin folder is still on my www among the WP installation. I am not sure now if it means that it is not active in my WP or not. I am not sure if I can reinstall it back again or not without doing some damage to the site.
Besides AAM I lost also other plugin from the plugin list - device-theme-switcher, though its files and folders are present on www file structure as well. Any ideas how to safely revitalize AAM back ?
Before starting the maintenance AAM version was 2.3
