So I figured out the FTP thing - I was in the wrong FTP place. Duh.
Anyway, so I moved the marking folder into the blocks folder, and then moved the lang file that came with it into the lang folder.
When I logged back into Moodle, I got " blockname block installed successfully".
Hmm, I say to myself. That's not right. So I go into Administration to see what's up, and there is blockname at the bottom.
Just to see what was happening, I added this blockname block onto a page, and went to the "manage courses" link at the bottom it. It brought up a list of my course numbers (HP101 for example), and gave me the options "yes" and "no" to choose from. I assumed that this meant whether or not I wanted to track those classes in this blockname block.
I added some classes to see what would happen, and a whole bunch of these (all identical) sprang up:
Warning: Invalid argument supplied for foreach() in /home/shaktiwi/public_html/training/blocks/marking/block_marking.php on line 631
The course numbers were listed in the blockname block under these errors, though.
So...what's up with all that? I'm sure I did something wrong and there's some quick fix.
