Howdy digitaliway,
While I can not see your site, I believe that sidebar is actually added by your theme, not our plugin. If your theme has a Template with the sidebar removed, you might be able to turn this off easily. If not, you will have to modify your theme.
The easy way: Going into WP Admin > Events > Settings > Display, and changing “Events template” to one of your other theme’s templates. Test each and see if one of them looks right.
If that did not work, the hard way: Modify your theme. Usually this is best done by creating a WP Child Theme. Find the where the sidebar is being added in the code, and then wrap it in a PHP conditional like: if(!tribe_is_event()){..}
A full list of tribe_is_ functions can be obtained from our documentation: http://docs.tri.be/
Does that make sense? Will that work for you? Please let me know. Cheers!
