Fatal error: require() [function.require]: Failed opening required

[spiros]

I get this when I try to install mods. The last time I tried to install social bookmarking mod.

Fatal error: require() [function.require]: Failed opening required '/home/translat/public_html/forum/Packages/temp/./install.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/translat/public_html/forum/Sources/Packages.php on line 552

And when I try to execute the php script install.php for the mod manually, I get:

I got this:

In some cases, SMF 1.0.x does not detect your FTP path correctly. This tool has successfully used the (possibly detected) path below. You may wish to write this down, and make sure to use it when installing mods.

public_html/forum

This problem should be resolved in the next major release of SMF.

Thank you.

Edit: I followed the instructions up to the Cleanup Permissions point,

Then I should enter

public_html/forum

Or

/public_html/forum
