for the synchronization process why the results don't exist at all, and the page I've bookmarked doesn't appear?

I have previously reinstalled the OS, and my Operamini application synchronized with email as usual. The page that I bookmark appears as before.
But after I reinstalled the OS this time, and my Operamini application synchronized with the email as usual. Even being an error there was no page that appeared at all

Please help,
thank you
