Afeter insal AIO SEO I left all functions by default.
Now Google indexed my homepage like:
BLOG DESCRIPTION : BLOG NAME
after BLOG DESCRIPTION shows colon ":" - it shouldn't. I set to display this sign "|" to separate description from name.
Besides it should to display BLOG NAME | BLOG DESCRIPTION
AIO SEO is set correct by default in wp-admin and in these setings there no any colon ":".
