Double LightBox images in Wordpress - how to remove?

Question

Lightbox

Good day to all, I've been suffering for a very long time, there are several plugins on the site: Responsive Lightbox - Pop-up photos, Jetpack - both can process a lightbox gallery, this function is disabled in the jetpack. Only one plugin works, and it turns on a double lightbox - you click on the photo on the site, it opens in a pop-up window, ok, you click on the cross and under the first lightbox with a photo you find the second .... how to fix it?
uninstall the plugin and reinstall? or how ?
Thanks for future replies.
PySy: site if anything - e-times.info (yes yes yes, I know about some errors in the code, let them be. Only the lightbox is of interest.)
