This is not a joomla issue but a server issue. The default php values for
max_input_vars is 1000 you need to increase this. If you check your server
error logs it will confirm tjis

Steps to reproduce the issue

Create a large number of menu items, nearly 1500 (see the comment below
also). Open a module. Change something. Try to save the module.
Expected result

The modification is changed and the module editor is still open after
clicking the Save-Button or is closed after clicking the Save-Close Button.
Actual result

In either case the module editor is closed, the modification is lost and
the module has a lock in the overview list, so one has to check it in
manually. Thus there are no more module changes possible in the default
language. Using the translation component of Lanternfish it is further
possible to save the changes.
System information (as much as possible)

Joomla 3.3.6 with the current version of LanternFish and some other
Extensions: sigplus, AllVideos, JCE, RokPad, Easybook Reloaded, Jumi, Qlue
Tip
Additional comments

We are setting up a Web-Site in several languages. Currently there are 20
languages. In the default language we have about 200 entries in the menu.
With all translations this results currently to 1500 menu item in the
database table till growing.

Closing as it's not a Joomla issue.
