dasty3/admin.php has a edit button to edit the config.xml file (resources/config/config.xml). The edition of this file change the first line ...
<?xml version="1.0" encoding="UTF-8"?>
to ...
<?xml version=\"1.0\" encoding=\"UTF-8\"?>
It seems the change makes the admin page fail when displaying the configuration parameters.

I can't reproduce this error in my own environment (Firefox with localhost (Apache 2.0) and local installation identical to svn.
I edited the configuration, made changes, re-open it using the same online facility and also the config.xml file directly and it still showed the correct first line, so I am not sure what the problem is but it must be related to an installation rather than the code.
I also had a look anyway at the code and it seems to save straight from the textarea to the file without adding anything (admin.php, line 38).

The problem happens when magic_quotes_gpc is on. I changed the code so that this is not a problem.
