My b2evolution Version: 3.3.1

When I use email subscriptions the emails arrive with the HTML tags showing as text, for example "<div ...>". The < and > are converted to &lt; and &gt;.

I have successfully made the following change to _misc_funcs.php to fix this, but surely this should not be happening in the downloaded version.

2293 // $headers['Content-Type'] = 'text/plain; charset='.$current_charset;

$headers['Content-Type'] = 'text/html charset='.$current_charset;
