HELP! Errcode 28 & error_log (logger.php)

So everything was fine and dandy until I turned off the Qty option and started changing all the products to a stock level of 1. Then I had BIG problems. Here are the error messages I got, any help is HUGELY appreciated!

1. Warning: error_log(/home/p268556r/public_html/store/cache/page_parse_time.log) [function.error-log]: failed to open stream: Permission denied in /home/p268556r/public_html/store/admin/includes/classes/logger.php on line 60

2. Can't create/write to file '/tmp/#sql_6e79_0.MYI' (Errcode: 28)
   ALL I WAS ABLE TO FIND ON THIS ERR WAS THAT THE TEMP FILE WAS FULL. WHERE IS IT AND HOW DO I CLEAR IT?

3. My drop down menu disappeared! WTH!

You can turn off Page Parse Time Logging in Admin->Configuration->Logging

   ALL I WAS ABLE TO FIND ON THIS ERR WAS THAT THE TEMP FILE WAS FULL. WHERE IS IT AND HOW DO I CLEAR IT?Yes, it indicates that the hard drive on which the /tmp/ folder is located has run out of space ... or the hosting account you've subscribed to has exceeded its alotted disk space usage.
   Your hosting company will have to help you in this regard, and you should notify them of the problem immediately..
