Does this happen on all surveys or just large surveys?
Can you try with a single question survey?

Thanks

Please can you review the max_input_vars php.ini setting and try again?

Hi grabieljenik
max_input_vars at php.ini is 1000 in our production server (crashes on large surveys) and 2000 in our testing server and it works partially.
I mean:
When you press "translate survey", sub-query translation works okay, but doesn't work with answer-options and all the email subjects. In fact, this is really strange cause answer-options translations only saves okey the FIRST screen, not all of them. So it's working partially.

Do you mean I must increase this value, for example, to 3000, 4000, 5000... to solve this ??
Or is it a real bug about saving process on database??
Waiting x your news

En lo de opciones de respuesta es muy raro, solo me guarda los cambios de la primera de la pantalla, las otras no.

Yes.

No, this is not a bug.
There are too many input fields on that screen and not all of them get to the PHP to have them processed.
