Hi everyones

i uses question type:Date in my survey

but i try to view question before actives survey

it showes

:Internal Server Error
Unknown "json_encode" function. Did you mean "json_decode"?
An internal error occurred while the Web server was processing your request. Please contact the webmaster to report this problem.

Thank you.

my version : 3.4.0+180219

PHP version ?
secure.php.net/manual/en/function.json-encode.php

php:5.5.36

Minimum 5.5.9 required - www.limesurvey.org/manual/Installation_-...rvey_on_your_website

Thx,I will check it

php:5.5.36

Isn't 5.5.36 > 5.5.9??

No, the last time I checked, .36 is less than .9

yeah, but i don't think these are decimals, are they? Since when are there two levels of decimals?

What I want to say, in my understanding, PHP Version 5.5.36 is newer than 5.5.9. Because they start with 0 and then go up with the number, not down.

PHP sees this very similar to me:

5.5.38 - Released: 21 Jul 2016
5.5.9 - Released: 6 Feb 2014

I guess your comment was sarcasm.

Okay, a numbering system that makes no sense.

Of course it makes sense. It makes total sense.

Version number starts with a low number and goes up. Then there is a second level of subnumbers that goes up and they even have a second sub level. Makes total sense to me. It is the same for LS as well.

1.0.0 < 1.0.1 < 1.1.0 < 2.0.0 < 5.5.9 < 5.5.38

As far as I know, this is how most version numbering systems for software work, isn't it?

By the way the "." as decimal separator is not as common as you think. In many countries it is a "," and the dot indicates thousands.

Thx everyone helps

Would i need to po more system data such as database version ...and so on?

SQL:Microsoft SQL Server 2008

I list my error code

LimeSurvey 3.5.0\application\views\survey\questions\answer\date\selector\answer.twig(52)

{% set aJsonOption = json_encode({
53 'format' : dateformatdetailsjs,
54 'minDate' : mindate[0] == '{' ? '1900-01-01' : mindate,
55 'maxDate' : maxdate[0] == '{' ? '2037-12-31' : maxdate,
56 'sideBySide' : true
57 })
58 %}

I check my php data

1.mbstring
Multibyte Support:enabled
Multibyte string engine :libmbfl
HTTP input encoding translation:disabled
libmbfl version:1.3.2


2.json
json support:enabled
json version:1.2.1


Would i enable HTTP input encoding translation?
