Hi,
Suddenly started to have an issue - once creating a new page, trying to install plugin - getting screen “Are you sure you want to do this?”. Tried to disable first all plugins - issue was gone, then enabled all and was disabling one by one, and once Cornerstone plugin was disabled - issue was gone, once enabled back - issue came back. So understanding that something wrong happened after the last update of Cornerstone
Could you please check what is happening with Cornerstone plugin?
