Top Horizontal Menu Not Showing

[JonQCoder]

I was having problems with my top horizontal menu not letting me add any links to it or delete links from it, so I attempted to reset the module. An error message showed up briefly, I don't recall what it said, but now my top menu is completely gone.  Under modules I have the option to "install" or "delete" it but when i try installing it, it says This module is already installed: blocktopmenu  . Deleting it displays a "module deleted successfully" message, and the module changes from "Top Horizontal" to "blocktopmenu" and gets put under "other modules". If I go to install it, I get the same already installed message. I'm not sure what else to try at this point. Replacing the module's files didn't change anything, but if I remove the files completely, it takes it away, but reinstalling it results in the same problem.  

 

I'm using Prestashop 1.6.0.14

In my case I had to disable Memcached - cache to make it work.
