Summary13810: Export Results in PDF format show page blank (and fail)
Description

Hi, we have a problem while exporting results in PDF.
First, the execution of export it seems to last a long time (several minutes, over 10);
Second, the execution ends always in a blank page without file to download.

Notice well that:

  • setting the PHP value max_execution_time to 300 or 600 did not impact on the result (always in blank page)
  • the export of the same results in excel format is successful and lasts a few seconds
  • there are no errors in apache logs
  • php do not show/display errors neither in logs
Steps To Reproduce

create: new survey
import: file lsa attached
goto: Responses & statistics
goto: Export results
choice: PDF format
click: Export

Try with max id to 5 : OK (with max_execution_time at 30)

PHP value max_execution_time to 300 or 600 : see config parameters : https://manual.limesurvey.org/Optional_settings#Resources . By default to 1200 : you can try with 12000 to have your export.

PS
debug=2 : Page shown Fatal error: Maximum execution time of 30 seconds exceeded in ./application/third_party/tcpdf/tcpdf.php on line 21646

debug=0 , my apache log : [Mon Jun 25 16:06:43 2018] [error] [client xx.xx.xx.xx] PHP Fatal error: Maximum execution time of 30 seconds exceeded in /…/application/third_party/tcpdf/tcpdf.php on line 21646, referer: https://master.sondages.pro/admin/export/sa/exportresults/surveyid/896833

Hi Denis,
thanks for your reply.

I've setted the php_value max_execution_time to 12000 like you suggest and then I've tried to export again the responses in PDF format.
The execution time was been from time between 12:17:25 and 14:02:17 and the exporting was result successfully (the document is by 15,6 MB and 6682 pages).

Clearly the problem is bound to the complexity of the same survey but it's strange thinking this procedure require so much time for only 514 responses.
