It seems this is a common issue in the forum and I need a solution as soon as possible.
Warning: ksort() expects parameter 1 to be array, null given in .../sitemap/pages/page-analyze.inc.php(2) : eval()'d code on line 55
Warning: Invalid argument supplied for foreach() in .../sitemap/pages/page-analyze.inc.php(2) : eval()'d code on line 57
Thanks in advance.
