Windows servers have trouble with \t
If a filesystem path contains the characters "\t" which has a special meaning in php code - the characters are replaced with a tab just like "\n" is replaced with a new line. This kind of problem is unique to Windows servers where the path uses backslashes (which is also the escape character in php) instead of slashes. To fix trouble with \t characters in Windows file path replace the backslashes with forward slashes (it can be changed through phpMyAdmin). If this doesn't work, try to escape the backslashes in the current path by adding another backslash before each of them.
