    check if the class exists in your filesystem. If that doesn't work, uninstall it and install it from github: github.com/tzyganu/UMC1.9 – Marius Oct 27 '16 at 7:22

    I don't know what else can cause the problem. If you have the compilation disabled and you cleared the cache, it should work. I was not a able to reproduce it. You can also check if you are read writes on the files and folders of the extension. – Marius Oct 27 '16 at 7:45
