Hi. Maybe for somebody its steel actual.
To correct the problem with disappearing content after editing the message , it is necessary in the module GeSHi BB Codes, at hook bbcode_create to add the following code:

PHP Code:

if ($this->is_wysiwyg()) 
  { 
    $this->unparsed_tags[] = 'phps';
    $this->unparsed_tags[] = 'jss';
    $this->unparsed_tags[] = 'htmls';
    $this->unparsed_tags[] = 'mysqls';
    $this->unparsed_tags[] = 'ahks';
    $this->unparsed_tags[] = 'au3s';
    $this->unparsed_tags[] = 'avss';
    $this->unparsed_tags[] = 'diffs';
    $this->unparsed_tags[] = 'xmls';
    $this->unparsed_tags[] = 'bashs';
        //....and so do this, for all used bbcodes...
  } 


Hope this will be useful...
