Works well

Same thing here. U need to go to Cpanel and change the name of “plugins” in something else (ex: xjahdd) after that uninstall or repair the plugin

problem solved! i manually delete the plugin from cpanel / plugins . after that i went to https://blog.webeng.it/how-to/cms/wordpress/sliding-youtube-gallery-wordpress-plugin/ and take the RC version! and manually installed from cpanel. So is a downgrade, but is working
