With Joomla 3.8.6, I'm trying to enable several site modules that were once enabled on the site before a recent redesign. The screen I'm looking at is the Extensions > Modules screen. First I search for the module name ("calculator") which produces a list of all the modules with that string in the Title. The Status column has the disabled icon (red circle with horizontal line). Clicking the icon does nothing. Hovering over it tells me I need to use Extensions ==> Manage to enable them.
So I go to Extensions ==> Manage ==> Manage and search for "calculator". Nothing comes up. Figuring they're not installed yet, I go to Install > Install from Folder, enter the path to the /public_html/modules folder where all the modules reside and click "Check and Install". It says "Installation of the module was successful.
I go back to Extensions ==> Manage ==> Manage and search for "calculator". Again, nothing comes up.
How do I enable these?
The answer in this case was that the module wasn't getting installed fully through the normal installation process. I had to use the "Discover" option as outlined in this article.
