This plugin doesn't work with Easy Smiles 1.0.5. The error in parser.php at the beginning of code.
//
// Get smilies from database
//
$smiley_text = array();
$smiley_img = array();
$result = $db->query('SELECT * FROM '.$db->prefix.'smilies') or error('Unable to retrieve smilies', __FILE__, __LINE__, $db->error()); // ERROR HERE!!!
while ($db_smilies = $db->fetch_assoc($result))
{
$smiley_text_array = array($db_smilies['text']);
$smiley_text = array_merge($smiley_text, $smiley_text_array);
$smiley_img_array = array($db_smilies['image']);
$smiley_img = array_merge($smiley_img, $smiley_img_array);
}
