Bug in include/version.php

This line

$variants_in_use = func_query_first_cell("SELECT COUNT(*) FROM $sql_tbl[classes] WHERE avail='Y' AND is_modifier=''");

will throw sql error if product options module is off - xcart_classes table not defined in $sql_tbl array. To fix replace this

 $variants_in_use = func_query_first_cell("SELECT COUNT(*) FROM $sql_tbl[classes] WHERE avail='Y' AND is_modifier=''");
 if ($variants_in_use)
  echo "<br />Variants (in use)";

with

if (!empty($active_modules['Product_Options'])) {
 $variants_in_use = func_query_first_cell("SELECT COUNT(*) FROM $sql_tbl[classes] WHERE avail='Y' AND is_modifier=''");
 if ($variants_in_use)
  echo "<br />Variants (in use)";
}
