files permission problem chmod()

[cmb]

he did not ftp them he extracted them using cpanel, this has known issues.

Oops, I should have read more carefully.

Also php warnings do not usually indicate an actual problem as such they are warnings, we attempt to copy as 755 then chmod to 777 and copy again, so warnings are normal, of course its possible that chmod is not allowed at all on your host.

Regarding admin/install.php line 39ff: wouldn't it be possible to avoid the copying and check the return value of chmod() instead? (That would not suppress the warnings, though.)
