Help please! wp-config file?

Hi all,

I’m not sure what I did, but I was cleaning up my files last night, and now my blog is not accessing all its pages.

It’s http://malcs.org, actually running from http://malcs.org/blog/
I followed the “install in different directory” directions, and it has been fine for years now. But apparently, I deleted something last night? I’ve repeated the basic edit to the blog/index.php file, and checked it and the root again, but nothing.

Clicking on the history or leadership page brings up a wp.config file error, but I see the config file in the /blog/ directory.

Any insight? please help…..my timing is terrible…..
Thank you!
Susana
