You can put your preference file back, we confirmed that you have a setting somewhere in there that is causing problems though.
I would turn off those 3 check boxes globally and make sure that you allow images to load in the "Images" section of preferences (also globally).
Then load google finance, do you see the site preferences icon in the status bar? That means OmniWeb thinks you have site preferences set for the current domain. Open site preferences and reset all your settings to match the global version, just look for the blue dots and click on those to revert to the default.
Does the problem persist?
If it does, open bookmarks and in the "Collections" sidebar, click on "Site Preferences".
Do you see mention of google here? If so, delete the entry.
Is the problem still present?
If not, I'd recommend sending a copy of your preference file over to our support ninjas and we should be able to figure out what's going on.
