Hi, I upgraded my staging environment to v11, and almost everything is working perfectly. Only one issue, which is actually quite nasty. Generating any ODT/ODS document fails. The problem is like below: Some invalid argument is given in commondocgenerator.php, and of course when the error message appears, the headers has been set and can’t be changed anymore.
I am running on a LInux server with PHP 7.3.8. All the documents are working fine on 10.0.6. Can anybody give me some advice?
