Problems after editing metatags on home page

I tried the link in this thread and did what was instructed and it left my site blank. I had to remove everything to like it was before. Now I am left with less than what I started with.

I had already edited my meta tags keywords for my home page. The rest was set to default so that it would read the meta tags that I had set up in admin.

I wanted to change my keywords. I noticed that when I went to my site and viewed source, my keywords didn't have commas in between. I wanted to add them as well as more keywords. I couldn't find that same page that I was viewing when I looked at the view source page.

Now with trying to use that link above, it blanked my screen. I just erased what I did but now I have no keywords listed when under view source.

I take it that with the upgrade to 8 that I won't have to worry about this problem or will I be able to find these files more easily? I am wanting to upgrade...I just can't figure it out. I had someone else set me up just to get me live and I have been learning how to add products and things like that. I can not figure out how to upgrade and change templates. Is upgrading the only way for me to add the meta tag keywords for my home page?

After searching & not finding, here I am:
I changed the meta tag file in includes/languages/english: nothing.
I added the meta tag keywords here but when I looked at the site live; page went blank;something about long string of text. I went in and deleted most of it. Site came back, but nothing that I inputed is showing when you view source.Here is the file as is now:

I have checked file in includes languages/english/my_template:
only one file there which is header.php. Is this correct?

I checked includes/modules & includes/modules/my_template:
nothing of what I see when I to to view source in Firefox. Here is the file:

I did not copy all of the view source...just enough to show what I want to edit and give you an idea of what page I am looking for.

I know I need to upgrade. I am looking for someone to do it for me as I am totally confused on doing it myself. But like I mentioned; I had corrected this problem before. I have no idea why it is like this. I tried to find this same file to add more keywords and have been having troubles since. I now show nothing instead of the few that I had a couple weeks ago. Can someone please assist me?
