Hi,
But, if I logoff from my account and login back thru guest account, I am able to open the same link
That's good. It's not a system wide problem, just your user account.
Open a Finder window select your Home Folder in the Sidebar on the left. Then open the Library folder, then the Caches folder, then the com.apple.Safari folder. Move the
cache.db file from the com.apple.Safari folder to the Trash. Relaunch Safari.
If that doesn't help, from your Safari menu bar click Safari / Reset Safari. Select the top 7 buttons, click Reset.
If that doesn't help, try troubleshooting the Safari .plist file. Quit Safari if it's open. Open a Finder window. Select your Home Folder in the Sidebar on the left. It has a small house icon. Then open the Library folder then the Preferences folder.
Move the
com.apple.Safari.plist file from the Preferences folder to the Desktop. Now launch Safari. If Safari opens links as it should, move that .plist file to the Trash.
