Email

/bin/sh: /root/clearcache.sh: /bin/sh^M: bad interpreter: No such file or directory

I just want to remove it

I think the ^M is a carriage return character, which windows uses at the end of lines in a text file but linux doesn't, so it's confused. To be honest I haven't used linux in a while, but I seem to remember a command called dos2unix which would fix that (assuming you don't know how to use vi or another linux editor). Try the command:
dos2unix /root/clearcache.sh


If you still want to remove the fix, try crontab -e and remove the line you added.

Edit: Oh, I see you said you removed everything that that page says to add? If that's the case then I don't know. Maybe emails are queued up somewhere or something like that, because it doesn't seem possible to get that message if you removed /root/clearcache.sh

chk crontab
crontab -e

You should really let your OS manage its memory. It knows how to operate more efficiently than you do.
