max_input_vars<\/h3>\n

The most common issue stems from the max_input_vars<\/code> PHP directive, which was introduced in PHP 5.3.9. By default, max_input_vars is set to 1000, which can easily be reached with the WordPress menu system, since each menu item sends about 12 variables per item.<\/p>\n

Solution<\/h4>\n

The solution is to simply configure the max_input_vars<\/code> so that it is large enough to handle the number of variables being sent by WordPress to save your menu.<\/p>\n

php.ini<\/h5>\n

If you have access to your php.ini<\/code>, you can just add this directive (or change the value of the existing directive) to includes your max input variables:<\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
max_input_vars = 3000;<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

If you don\u2019t have access to this file (as with many shared hosts), you may need to contact your host to increase this limit.<\/p>\n

.htaccess<\/h5>\n

Alternatively, you can try placing this in your .htaccess<\/code>. This won\u2019t work on some servers, so your mileage may vary.<\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
php_value max_input_vars 3000<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n
.user.ini<\/h5>\n

If you have a .user.ini file, you can add the following to override the default php.ini value<\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
max_input_vars = 5000;<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
