With CiC hosting, when you have a large number of menu items in the Menu Manager of the ACP you can no longer reorder them. When you attempt to reorder the menu items, the UI updates as expected, but upon reloading the page the items are in the same place.

Using developer tools, we can see that the hosting environment is returning a 414 URI Too Long error message. This is because the menu items and positions are pushed into the GET query string, rather than being submitted via POST.

How many items do you have in your navigation there?

We made a custom side-menu bar (much like Invison5) so it has a lot of menu items, some have pull-downs, 100+ items:

Any chance of increasing the limit?

Unfortunately, that is not possible.
