Can't log on w/ Safari 5.1.4

I am having the exact same issue with the latest version of Safari. Login doesn't work for the three vBulletin based forums that I frequently visit.

I only have two plugins, AdBlock and Translate, and disabling them didn't seem to help.

It works fine in Firefox though. And it worked fine before upgrading Safari.

Edit: Problem solved! You need to turn off 32 bit mode (find Safari.app, hit command+I, then uncheck "open with 32 bit mode" (or something like that)).

 

Turned on Open in 32 Bit Mode = Works

I checked the Application Info Panel and found that 'Open in 32 Bit Mode' was off. Turned it on = works. Weird.

btw - I had been having trouble signing on to networks at some airports and at Marriott Courtyard Hotels that use iBHAN for their ISP. The URL subscription script would go to 75% completion, quit and restart. Endless loop.

Switched to FireFox - it worked. Typing this now in Firefox but Safari is also running.

Seems to indicate that changing a setting is key to the resolution. It does not seem to matter what setting is changed.

 

Yay! It worked for me as well. Thanks for the solution.

 

Thanks!

Thanks a million! Before doing this I couldn't log in to gmail and many other websites!

 

I couldn't see my Gmail inbox or use Google Reader. I didn't try the 32-bit version trick. After the update I can see my Gmail inbox again.
