Test result matrix is not exported to excel if more than 6 active build

[licina-nunes]

I am currently using testlink 1.9.14. I have 17 active builds.
I selected two builds to generate a test report matrix for those => it worked fine. REsults are displayed in browser.
But when I try to export to excel, I have no file download at all and the result previously displayed are completely erased (all white).
Do you have an idea of what could cause the problem?
Thanks a lot.

Best regards

Note: If I proceed the same way to get flat result report, it is ok.

Hello.
Thanks a lot for your answer: We made the upgrade. Problem is solved! Thanks.
But now, I can no more import xml test files as I did before using MrBricodage excel macro.
I get error:
==============================================================================

DB Access Error - debug_print_backtrace() OUTPUT START

and import is stopped after first test suite/test case
I tried the same import in version 1.9.14.
Does the xml format for import has change between 1.9.14 and 1.9.20?
Thanks again for your support.

For the import problem, we finally found the origin: in MySql, strict mode has to be disabled.
This solved the error above DB Access Error - debug_print_backtrace() OUTPUT START
If it can help someone.
