I'm using WordPress in German (or another language) and I cannot change page builder drop downs, or theme options aren't working correctly.

This was fixed in version 1.4 of Explicit, so please update. Or you can edit functions/admin/it-options.php and locate line 62 which looks like this:

'' => sprintf( __( 'Display Site Title <small><a href="%1$s/wp-admin/options-general.php" target="_blank">(click here to edit site title)</a></small>', IT_TEXTDOMAIN ), esc_url( get_option('siteurl') ) )

Change it to this and that should fix your issues:

'' => __( 'Display Site Title', IT_TEXTDOMAIN )
