hello, ElKeter, & welcome to the WordPress support forum.
Did you have a particular reason for installing WordPress as a multisite installation? Truthfully, the only time you should really do that is if you have multiple users on your site, each of whom has a blog–think wordpress.com as a prime scenario for this. Newspapers who have columnists,each of whom have their own blog is another. Unless you have a similar need, multisite is probably not the way to go.
You can actually get rid of the multisite installation by commenting out the entries in your wp-config.php file by putting // in front of a single line like so:
// this is a comment
or by using /* with multiple lines like:
/* this comments out 3 lines
Line 2 is a comment
so is line 3 */
The tools section of your WordPress dashboard should now reflect that the network option is no longer available. You might also need to comment out those parts of your .htaccess file that pertain to multisite. Commenting out the .htaccess is a bit different than the wp-config.php file, in that you put a # in front of the line you wish to comment out, as in:
# this is a comment & will be ignored.
Assuming you’ve disabled multisite, to make your site come up on your domain, follow the article here:

Basically, if you have a typical shared hosting install of WordPress using Linux, copy your index.php file to the web root & change it to look like:
require(‘./wp-blog/wp-blog-header.php’);
Please let us know if this did (or did not) help.
HUUUUUUGE thanks!
Made the changes to config.php. No more multisite. Functions are available.
What a relief!
Thanks again.
