Can't log into dashboard

I have been having similar problems after upgrading to 3.1.4.
I’m not sure exactly what is causing the problems, but my pages fail to complete loading and then timeout.

I wasn’t hacked, rather WP and PHP are fighting.
I had WP 3.1.4 and PHP 5.2.17 running fine.
The upcoming WP 3.2 requires PHP 5.2.4 so I asked my web host to upgrade PHP to the latest which is 5.2.9.
Now I can’t get to my WP Admin page.
I’m using Safari so I tried FireFox and can’t even log in there.
Something’s wrong with WP.
Frankly, there should be more graceful backward compatibility.

When I go to:

https://flashweb.com/wp-admin/

I get the message:

“Not Found Apologies, but the page you requested could not be found. Perhaps searching will help.”

I am running into the same issue. I can’t log into my WP Admin page. I just get a blank white screen. Please help.

Thanks!

When I try to go to https://wellnesswithinchiropractic.com/home/wp-admin I get redirected to https://wellnesswithinchiropractic.com/home/wp-login.php?redirect_to=http%3A%2F%2Fwellnesswithinchiropractic.com%2Fhome%2Fwp-admin%2F&reauth=1.
And it’s a blank page. I’m at at loss. This started happening once I upgraded to WP 3.2.

Please help!
