Unexected errors

I am learning my way around 1.3.6 on my local PC, so I don't have a URL to give you.
I put in about 12 hours on my ZC yesterday and was well on my way to getting where I wanted to be -- a fairly basic ZC without bells and whistles. It looked great last night. It looked great first thing this morning. Then I went into my custom stylesheet (based on default with Classic green colors) and changed my MainWrapper width from 750px to 100%. All I wanted to do was settle on a size I liked. So, I made the change in Crimson Editor and went back to FF browser and refreshed my local ZC. My custome template is named magicfoxxx and the ZC resides in parent directory magicfoxxx. What did I do accidentally to get this:

Warning: include(includes/modules/extra_functions.php) [function.include]: failed to open stream: No such file or directory in C:\wamp\www\magicfoxxx\includes\init_includes\init_general_funcs.php on line 34

It's telling you you're missing some files:

include(includes/modules/extra_functions.php) [function.include]: failed to open stream: No such file or directory
include(includes/modules/extra_definitions.php) [function.include]: failed to open stream: No such file or directory
require(includes/modules/meta_tags.php) [function.require]: failed to open stream: No such file or directory

Thanks, DrB
I'll go try to find them and more importantly, how I lost them. All I did was change the MainWrapper width.
I'll let you know how I make out.

I must have used all 10 thumbs. I'm back in business. My includes/modules folder disappeared. I couldn't find it in my Recycle Bin, so I don't know what really happened.

Do you have any ideas what the trickle down effects I can expect by taking the original includes/modules and just copied it into my ZC? I had started setting up my USPS and Paypal modules.

Thanks again
John

Sounds like somehow you had dragged-and-dropped things to another folder mistakenly.

As for simply copying the originals ... if you hadn't made any customizations within that folder, you'll be fine.

Backups are always handy in this sort of situation.

Thank you for that link. I've been trying to find all of the pieces that are in this one article.
