Re: Simple SEO URL [support thread]
So that's the reason why. You havent got it installed yet. I will add this re-install feature today, but for now just go to your admin/includes/module_installation and delete a file called: .keep. Now go back to your admin and go to the module manager for it to automatically installs itself. If you see a warning say: "can not create .keep file" then just create a new .keep at admin/includes/module_installation
I no longer provide installation support on forum for all my modules. However, if there are real bugs with the modules please feel free to contact me
