Hi there, yesterday i was working on the cms just fine. Today i wanted to upload a new image to revolution slider, but the buttons just.. Do nothing, at all. I’m no expert, but i think that javascript isn’t working fine. The whole site and plugins are up to date. I write you the errors i see from developer tools.
