My menu structure loses some items (or options) when I save the settings.
Cause of this problem is small value of the "max_input_vars"
option in the configuration of your server (host). You must increase
value of the "max_input_vars". You must to set a value that is twice as
large of the current value.
Most hosts have the opportunity to change this value in the "Host Admin Area".
If currently you have max_input_vars = 1000
You need to set max_input_vars = 2000 (or more)
You can try to change this value using ".htaccess" file in root
directory of the your site, adding this lines in ".htaccess".
php_value max_input_vars 3000 php_value suhosin.post.max_vars 3000 php_value suhosin.request.max_vars 3000
You can try to change this value using "php.ini". Add this line if you don't find max_input_vars
max_input_vars = 3000
If that does not help you, ask your host support "How can I increase the value of the max_input_vars for my site?".
Also you can deactivate the options that you do not use to
customize the menu structure. It helps reduce the number of options and
reduce the load on the server.
- If you do not use option "Icon Of The Item" - disable it globally in the "Mega Main Menu -> Settings of the structure -> Icon Of The Item -> Disable".
- If you do not use option "Description Of The Item" - disable it globally in the "Mega Main Menu -> Settings of the structure -> Description Of The Item -> Disable".
The most unused options, you can try to disable them:
- Description Of The Item.
- Style Of The Item.
- Visibility Control.
- Dropdown Background Image.
