in 1.0.4 posting a serie of empty brackets like this
[ ][ ][ ]

makes the whole application fail (error 500) cause of a parse error
cause of the recusrsivity of the parse function that generates more [ ] during the parsing...

here is the solution:

in the parser.inc.php

add the line

$text = ereg_replace('[[:space:]]*]','',$text);//Bug Fix By WinterDryad

to the

function setText($text)

like this:

function setText($text) {
# define new text to parse
$text = ereg_replace('[[:space:]]*]','',$text);//Bug Fix By WinterDryad
$this->text = $text;
return TAGPARSER_RET_OK;

it basically strips all the useless empty tags from the core code before parsing.

after some attempts this is the best solution i've found.

hope u like it
