fopen Permission Denied?!?!?!??!

[sixthcrusifix]

I'm trying to install Wbblite and it worked last year but now all the sudden I get this:

Warning: fopen(lib/options.inc.php) [function.fopen]: failed to open stream: Permission denied in /fpgs/fpgshttpd/sixthcrusifix/memorium/forum/acp/lib/class_options.php on line 12

Warning: fwrite(): supplied argument is not a valid stream resource in /fpgs/fpgshttpd/sixthcrusifix/memorium/forum/acp/lib/class_options.php on line 13

I have no idea how to edit the appropriate files by hand and I NEED to install this sucker...

Also I owuld like to note that ALL permissions for ALL folders in this ENTIRE portion of my site are set to 777.

What are the permissions on lib/options.inc.php? They should be at least 775 I think...

Well by default all teh folders were set to 755 and so I set them all to 777, can you chmod a single file? The folder that  lib/options.inc.php is in is set to 777 do I have to chmod the single file? ? ?

Yes, you must chmod the actual file
