I can't get a favicon from Ally Bank. I've tried http://www.ally.com/ and https://secure.ally.com/allyWebClient/login.do. Here is the error message:
Could not download favicon(s). This may be a temporary problem so you may want to try again later or post the contents of this error message on the KeePass Favicon Download forums at http://sourceforge.net/projects/keepass-favicon/support. Technical information which may help diagnose the problem is listed below, you can copy it to your clipboard by just clicking on this message and pressing CTRL-C.
ProtocolError: The remote server returned an error: (404) Not Found.: System.Net.HttpWebResponse
I've just released a new version of the plugin which works for Ally bank (as well as hopefully most other websites).
Please try out version 1.5 and let me know if it works for you.
