After upgrading yt plugin to latest version 2.2.3, I have a blank site and error:
Fatal error: Cannot redeclare class Browser in /home///extra/templates/sj_wallblog/includes/browser.php on line 139
Using SJWallblog template - wwhen setting protostar as default, I have the site back (with bad layout) and get Strict Standards: Only variables should be passed by reference in /home////extra/plugins/system/yt/includes/libs/yt-minify.php on line 179
Can I try going back to older versions of yt plugin?

Dear dewebmeester,
Please uninstall yt plugin version 2.2.3 and install old version. This theme is incompatible with yt plugin version 2.2.3 and you site can not work.

Thanks.

After upgrading YT template framework Plugin for template SJ_Wallblog, we are getting error on frontend
Fatal error: Cannot declare class Browser, because the name is already in use in browser.php on line 139
