Michel,

I've run the Setup option from the top bar to an new window. I've changed my signature and pressed the 'save' button.

Ive tried to save to original setup to the same result.
I get Server Error in '/' Application.
It looks

Runtime Error 
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of
the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local
server machine. 

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag
within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should
then have its "mode" attribute set to "Off".


<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>
 

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the
application's <customErrors> configuration tag to point to a custom error page URL.


<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
    </system.web>
</configuration>
