The maximum number of inputs on this page has been exceeded. You cannot make edits to this page because of your server’s PHP “max_input_vars” setting.
The ‘max_input_vars’ setting is a limit set on your server that tells it how many ‘inputs’ it can read within a request.
Your limit is currently 4096 (which is fine) and by default, EE will use roughly 300 inputs when creating a new event, a quick example here: https://monosnap.com/file/4lX2FEShM5Mn3mdEU7v4stUOj2FM6E
Each time you add anything to the page such as a datetime or ticket, you (the admin) add more ‘inputs’ to the page. Now generally you get about 10 tickets and 10 datetimes before you hit around 1000 inputs (that’s the default setting for most servers).
On your page there’s are 11000 inputs so either your have a huge number of tickets/datetimes in that event (unlikely) or most likely your theme (or a plugin) is loading some kind of options page on the EE event editor and that has a ton of inputs.
Which theme are you using?
(Note you’ll be getting the same issue on ‘normal’ pages/posts on your site if the same thing is loading there as your server can only read 4096 inputs, not 11 thousand, its just that EE is checking for the number of inputs and throwing the above to let you know about it)
