این چه اروریه Warning: mb_strpos() [function.mb-strpos]: Empty delimiter in \librar

[titanpass]

الان با غیر فعال کردن خطایابی مشکل حل شد ؟
libraries\phputf8\mbstring\core.php این فایل از این مسیر می تونید بدید یه نگاه بندازم ؟

بله بعد خاموش کردن خطایابی دیگه ارور ها نشون داده نمی شوند.
اگر میشه بگید معنی اون خطا چیه
الان سایت رو لوکاله اگر ایراد اساسیه اصلا بالا نفرستمش

اینم کد فایل core.php
