Cannot modify header information (Sapi.php:132) NC 19.0.2 /20.0.1

[dzi77]

Hello,
I'm opening here this topic as I strongly believe that the below error is related with Groupfolders plugin. I'm not receiving any error when I'm uploading any file on the local storage. Please check the below error output:

Error:` Cannot modify header information - headers already sent by (output started at /var/www/html/nextcloud/3rdparty/sabre/http/lib/Sapi.php:132) at /var/www/html/nextcloud/apps/dav/lib/Connector/Sabre/File.php#690

We had also a long discussion on this topic: nextcloud/server#22509

Dif you see any UI errors, or is it just a log that is worrying you?

Probably related to #1445

I assume this is a duplicate of #1445 and the issue is fixed now. If you think this is wrong please create a new issue. Thanks!
