Hello SMFHacks.
First of all - thanks for the awesome mod. Regretfully I have the same problem, i.e. I simply can't install it! I have the latest version (1.1.1) of SMF and just got the mod off your site. Where do the files go?
Do I manually upload them as the following code says:
<require-file name="globalhf.php" destination="$sourcedir" />
<require-file name="globalhf.template.php" destination="$themedir" />
<require-file name="smfheader.php" destination="$boarddir" />
<require-file name="smffooter.php" destination="$boarddir" />

Thanks in advance for your help. I really want to have it in my forum.
