Interesting. I installed ubunutu in VM on my windows machine for a time and while I think its great for people that are new to computers or converting from windows, I still prefer to do it all old school with fedora.
With the latest headaches I'm seeing with mod_security I'm beginning to think its over kill. Being safe is one thing but when it comes to the point that its hampering productivity, I just cant see using it, especially on a small private server. It may be useful for on a larger server where your hosting a bunch of other people but I haven't gotten into that end of it yet.
Currently I'm building a demo site for my mods over at Bluto's hosting and we went through hell tracking down why it wouldn't work. In the end Bluto found the fix for it after I pretty much snapped and gave up. I even was ready to take the mod off SMF, I was so frustrated.
It could be something with .htaccess or your httpd.conf file that is blocking it.
It could also be something as simple as dropping an index.html or php in the folder. I planned on doing this in an update anyway to prevent people from getting into the directory from the outside easily.
The only other thing I can think of is that I changed part of the wowhead_wrapper.php on a suggestion from The SMF Customize Team when they were checking out the mod for approval...
$wowhead_use_fopen = !function_exists('curl_init');
You can try to change that to...
$wowhead_use_fopen = 1;
To force the mod to use fopen or
$wowhead_use_fopen = 0;
Will force it to use curl.
That's the way Matt Mayers originally coded the script but the way I have it now should actually look to see if libcurl is installed and if not then try to use fopen functions instead.
ltdeta, to change to a different language you can edit the wowhead_wrapper.php.
$url = "http://www.wowhead.com/?item=".urlencode(addslashes($_GET['item']))."&xml";
and change the "www.wowhead.com/?item=
" to your preferred language.
