You can't boost posts because your shared login has been disabled

I just converted my FB profile page over to a business page (company) Im able to promote the page but not a post. Cant boost post. For some reason I now have two business account FB pages, one with likes, one without likes. Im wondering if this has something to do with me not being able to boost posts. Its asking me to log into my personnel FB account, but I dont have a personnel FB anymore because it was converted to a business FB page..Please advise
