would also like to share that notepad++ is an excellent editor for your site. it has an FTP plugin so you can ftp open the file, make your edits, click on save, the file pushes back up to the server. open browser, clear browsers cache,
from notepad++ you can clear your cache and cache_pubilc directories, leaving the .htaccess file in place.
call your site and see if the changes are what you were expecting. if not, you can go to notepad++ hit the undo button or ctrl+z and this will undo your actions. then click save again, and you have restored your file to its original state.
note of advice on this as well. if you are editing the uni template, its best to follow the practice of creating your own template, by copying the uni template and renaming the appropriate locations. that way if you wreck your template like many of us have, you can still fall back on uni.
Thanks a lot, found what I needed
