طریقه ی حل کردن این خطا رو پیدا کردم.
باید فایل (/classes/Validate.php ) رو باز کنین و چنتا کد رو جایگزین کنید :
از :
public static function isCleanHtml($html, $allow_iframe = false) { $events = 'onmousedown|onmousemove|onmmouseup|onmouseover|onmouseout|onload|onunload|onfocus|onblur|onchange';
$events .= '|onsubmit|ondblclick|onclick|onkeydown|onkeyup|onkeypress|onmouseenter|onmouseleave|onerror|onselect|onreset|onabort|ondragdrop|onresize|onactivate|onafterprint|onmoveend';
$events .= '|onafterupdate|onbeforeactivate|onbeforecopy|onbeforecut|onbeforedeactivate|onbeforeeditfocus|onbeforepaste|onbeforeprint|onbeforeunload|onbeforeupdate|onmove';
$events .= '|onbounce|oncellchange|oncontextmenu|oncontrolselect|oncopy|oncut|ondataavailable|ondatasetchanged|ondatasetcomplete|ondeactivate|ondrag|ondragend|ondragenter|onmousewheel';
$events .= '|ondragleave|ondragover|ondragstart|ondrop|onerrorupdate|onfilterchange|onfinish|onfocusin|onfocusout|onhashchange|onhelp|oninput|onlosecapture|onmessage|onmouseup|onmovestart';
$events .= '|onoffline|ononline|onpaste|onpropertychange|onreadystatechange|onresizeend|onresizestart|onrowenter|onrowexit|onrowsdelete|onrowsinserted|onscroll|onsearch|onselectionchange';
$events .= '|onselectstart|onstart|onstop'; if (preg_match('/<[\s]*script/ims', $html) || preg_match('/('.$events.')[\s]*=/ims',
$html) || preg_match('/.*script\:/ims', $html)) return false; if (!$allow_iframe && preg_match('/<[\s]*(i?frame|form|input|embed|object)/ims',
$html)) return false; return true; }
به:
public static function isCleanHtml($html, $allow_iframe = false) { return true; }
