Revolution Slider can't be activated

Dear All,

My website used quite a few of revsliders on several pages. I discovered that they are not showing on the pages and I can’t activate them. When I click the ‘Activate’ button on the Plugins page, the following message pops up:
“Plugin could not be activated because it triggered a fatal error .”

Does anyone have any idea what the problem could be please? Trying to get the site up and running as normal asap.

Thank you so much,
