Whenever I try to install slider revolution, I get a message: “Plugin not activated. A higher version of Slider Revolution is needed for this theme. Please update the plugin. I cannot update it though, because I can’t install the plugin.
Sorry to hear of the problem you are having.
It seems server related issue so please contact your web host to resolve it or try installing it manually as described in the below page.
Could you please tell me which version of Slider Revolution plugin you are using on your site?
Would you mind if i log in to your site and do some troubleshooting? If this is ok then could you please share me your site log in details privately by adding them in the box having text “Click here to share private content. Only you and forum moderators will be able see it.”?
