پيغام خطا در كامپوننتها

[shokri]

با سلام....
در هنگام نصب بسياري از كامپوننت ها ضمن اينكه پيام "كامپوننت با موفقيت آپلود شد " ديده مي شود ، پيغام خطاهاي زير نيز به چشم مي خورد:
Warning: copy(/home/shokri/public_html//administrator/images/approve.png) [function.copy]: failed to open stream: Permission denied
in /home/shokri/public_html/administrator/components/com_remository/install.remository.php on line 34

This directory does not exist, preventing Remository from functioning
Upload path is: /home/shokri/public_html//components/com_remository_files/downloads/uploads/

و بعد از نصب نيز اكثرا با مشكل مواجه است...

لطفا راهنمايي كنيد...

با تشكر..
