Warning: include cfg/tables.inc.php в Shop Script

I am not a fan of Shop Script, but his glitches are easily fixed. An error was found on the site in the filter, in the admin panel when working with the removal of additions to the product, etc. The error is always the same:

Warning: include(./cfg/tables.inc.php) [function.include]: failed to open stream: No such file or directory in /home/myru/public_html/shop/cfg/connect.inc.php on line 12

The solution is a little strange, but working:
in the file /cfg/connect.inc.php delete or comment out the line include(“./cfg/tables.inc.php”);

After that, be sure to place the same edits in the files:

/admin.php
/index.php
/includes/category.php

Clear the cache (if the problem was not resolved) and then reload the page.
