Hi everyone.

I've experienced problems with LS after upgrading it to the latest version (1.87 to 1.92 build 120412).

I have two copy of the 1.87. One in a development server which can only accessed internally among developers. The second is a production server accessed by public. Both server have the same PHP, Mysql and apache version.

My LS upgrading activity in Dev server was a success. Everything running good. the admin page and also the surveys were okay.

But after I've upgraded the version inside the production server, problem occurred. Every survey with multiple question type such array, list, radio button were not appeared accordingly in the browser. admin page was ok. When i try to test one whole survey from production server, especially survey with array type questions, it show error/blank page.


when I click test survey button, this is the url look like.



In the welcome page, I click the NEXT button. The url will change to only index.php and remove all others extra variable.


The survey questions should appear after I click the NEXT button but only surveys from development server appear accordingly, not the surveys from production server. This is the error page appeared from surveys in production server. (chrome browser error: Error 324 (net::ERR_EMPTY_RESPONSE))

Can anyone help me to repair the LS in production server?

Thank you in advance!

Hello!

Looks like there is an error in config.php
Open it in a text editor and correct the $rooturl. (where the unnecessary limetest needs to removed).

Hi Mr c_schimtz.

Sorry that my previous image was not perfectly cropped.



This is the actually URL for my problem. The "limetest" in the $rooturl is actually the LS folder name.

Sorry for the mistake. Please help me. TQVM!

1. Are both systems really using the exact same configuration?

2. Did you try exporting the working survey and importing it at the system where it was not working?

3. Please switch on debug mode by adding the following line to your config.php file:
Are there any additional errors reported on top of the page?

Dear Mazi,

1. Yes both systems are using the same configuration.

2. I've tried it but still showing the same error.

3. $debug has been inserted but no additional error appear.

FYI, I've pointed both system to the same database server. The dev server running ok but the prod server still with same problem.

TQ.

Dear all,

I've check with the error_logs and found this log:
PHP Fatal error: Allowed memory size of 16777216 bytes exhausted

After that I changed my production server memory_limit in php.ini and glad that the LS in the prod server finally appear correctly.

No data received – ERR_EMPTY_RESPONSE or Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data

I received the error on chrome but it's gone after I used simple commands on command prompt. May be it's working for you also.

ipconfig /flushdns
ipconfig /renew
