i have a Member Only site where Registering is required

Hi, i have a Member Only site where Registering is required before accessing the page.
behind the register/login, members have access to a business directory. where they can set up a page for their company, with photos & information.
there is also a option to share their advert on Facebook, google,..

i created the First login with a Coming Soon page with Login, and a link to the registration... so when a user is now logged in and want to share a Place or Location facebook just crawl the content from the coming soon page .. not from the Place or Location.. is there any way that content can get shared normaly for facebook.. means: place description & Foto, like it works when i have not activated the Coming Soon Plugin?

thx in advance for any tip
regards
Mike
