Hello,
On our test site with legenda theme, we also use slider revolution plugin but don’t face the problem, so you need to try to disable 3rd party plugins (means the plugins that are not included in the theme package are not in the list of required plugins), clear cache and then check. Also, you may try to re-upload Revolution Slider plugin https://www.8theme.com/download-plugins/page/2/
