i have installed the plugin into two different webpages, but after activation - i can´t find any extra item prop tags in the sourcecode ? Former i had installed another rich snipped plugin "All in one schema.org Rich Snippets" on both websites, but the plugin is de-activated and the whole files are deleted (via FTP).
Is it possible, that there are still some DB - Entries from this former plugin, that makes the item prop WP for SERP / SEO Rich snippets plugin won´t work ?
Here are the two Websites (German only)
Looking forward for any help - thanks in advance !
