Logged into my wordpress website this morning and this lovely message was showing up:
Warning: htmlspecialchars() [function.htmlspecialchars]: charset `UTF-6' not supported, assuming iso-8859-1 in /home/content/26/8371226/html/wp-includes/formatting.php on line 2751
This displays all over the admin pages and post pages. Does anyone know how to fix this? I've already uploaded a new formatting.php from a freshly downloaded WP 3.6 and it didn't solve the problem.
Any help would be greatly appreciated. Thanks!
