I was pulling my hair out last night trying to get the blog module to show properly using the BlogHolder and BlogEntry templates. Every time I tried to access the blog template, it would display a blank page. Did a few searches on the forum, turns out a few other people have this issue, but a fix was not available as it seems to be a scattered issue... which leads me to believe it's something on the server end?

After digging through the code, I found the culprit to be related to the BBCodeParser... if I removed any calls to it then the page would load fine. If the BBCodeParser was included, then it would not display. Any idea how I can get the BBCodeParser to function properly? Or should I remove it entirely.

I'm building this on a HostGator shared server.

Use a trunk build in the svn.

Ok so the problem lies in the code to add filters:
line 216 of sapphire/parsers/HTML/HTMLBBCodeParser.php:
@include_once 'BBCodeParser/Filter/'.$filter.'.php';

The @ silences the errors which is a problem in itself.

Then when the filter file is include (eg Basic.php)
line 31: require_once 'HTML/BBCodeParser/Filter.php';

This is meant to include sapphire/parsers/HTML/BBCodeParser/Filter.php but actually includes from the pear include directory - since that comes first in my include path.

So the solution is to change the following line in sapphire/_config.php:
set_include_path(get_include_path() . PATH_SEPARATOR . $path);

to:
set_include_path(str_replace('.' . PATH_SEPARATOR, '.' . PATH_SEPARATOR . $path . PATH_SEPARATOR, get_include_path()));

Thus putting the parsers directory ahead of the pear dir in the php include path. Or alternatively you could change the individual filter files to use relative paths for includes.
