I have a problem. I had to disable all my plugins to see which on is causing white screen of death so I disabled and enabled SEO by Yoast again. Now all my custom meta descripnions are gone from Google - they are stil saved in the plugin but seems like Google ignore them.
I have almost 200 post so it's nearly impossible to ping each one of them again. I also clicked on "Fetch as Google" in webmaster tools but it's already a week and I can't get my old Metas back.
I'll thankful if you help me.
