Hello Srijith, the issue regarding custom code appearing on facebook popup seems to have misteriously resolved by itself.
Now I have another problem: the addthis share is almeost never showing up in the home page, under any excerpt or fetured content, as it was doing just days ago.
I haven't made any substantial modification to the site. Sometimes If you reload several times, eventually it will show up. Is it a problem with the Addthis server?
I don't have any cache plugin.
This is happening with the follow sharing tool at the bottom, the first design selected.

Do you need the access to my test site? Let me know!
Thanks for the support.
