Generally, that means you are hitting the servers max_input_vars settings, which basically means your server reads the first X number of inputs (by default its 1000) and then ignores the rest.
What version number of Event Espresso are you using? The latest (currently (4.9.76.p) should show you a notice on the event editor if you are hitting the limit.
Or, when in the event editor, if you open Chrome dev tools (or similar) and in the elements section search for ‘inputs’ you’ll get a rough idea of how many inputs are on the page. If its more than 1000 you’ll likey be hitting the value, you can check in Event Espresso -> Maintenance -> System information, search for max_input_vars.
The first step is to update to the latest version of Event Espresso (4.9.76.p) to confirm the issue is with max_input_vars. Update then visit the event editor and click to create a new ticket…. you don’t need to save it but just wait a few seconds and EE will show a notice if that is the problem.
To fix I’d advise contacting your host and have them update the value of max_input_vars to something higher (3000 maybe) and retest. The problem is that some themes add rediculious amounts of inputs, we’ve seen themes add 11 thousand inputs to the page, meaning even with the above you would still run into the same problem so you need to confirm with the above.
