i formerly used all in one seo pack for seo. but i switched to this plugin (yoast wp-seo) cause i was not really happy with all in one seo pack. So i deactivated allinoneseo pack and then removed it. then i installed yoast wp-seo. However my old all-in one seo titles still remain and (with nothing filled in) in the configuration of yoast, my titles already look crap. At some pages, the title is three times the page name.
See for example.
Please someone help me fix this...
