Can't Login???

As of today, I am not able to login to my Admin account or login at all???
The rest of the store seems to be working fine.
I get a "The connection was interrupted while the page was loading." error???
...

Ok, I am being told by my hosting provider it has to do with SSL.
Is there a way to turn off SSL without logging into my account?

Look at web.config file. All SSL settings are stored there

Great. :) This is what I found regarding SSL:
...
<authentication mode="Forms">
      <forms name="NOPCOMMERCE.AUTH" loginUrl="~/Login.aspx" protection="All" timeout="43200" path="/" requireSSL="false" slidingExpiration="true" defaultUrl="~/default.aspx" enableCrossAppRedirects="false"/>
    </authentication>
    <anonymousIdentification enabled="true"/>
    <authorization>
      <allow users="*"/>
    </authorization>
...
Is this what I need to change? If so, what should I change?

Thank you

Don't go too much by what hosting providers tell you unless they are very familiar with the app you are running.

Some of the statements reported by users here from some hosts are just nonsense.

I do not see anything wrong with the statement above. SSL is turned off.

If you have an SSL certificate installed turn it on (set to true).

Hmm...I agree, but it does seem to be a problem with 'Log In'.
The rest of the site works fine and logging in goes through 'https'.
...
Could it be something with protection="All" ?

No, ALL is a default and should be as is.

Is there anywhere else that SSL might be turned on, preventing me from logging in?

Try adjustng your privacy settings in your browser.

If you do not have cookies enabled (or the wrong privacy level) you may not be able to login. Just a thought.

I am getting seriously desperate as we've spent some time making our store.

I tried several settings now, including different browers.

This is the error message I get via Safari:
Safari can’t open the page “https://site.com/Login.aspx” because Safari can’t establish a secure connection to the server “site.com”.
...
What could this mean??

My hosting support still seems to think if I purchase SSL everything should work fine again.
