Headers already sent by (output started at .../cron.php:34) at /lib/private/Session/CryptoWrapper.php#87


I see the following message in my logs using the cron:

Cannot modify header information - headers already sent by (output started at …/cron.php:34) at …/lib/private/Session/CryptoWrapper.php#87

Does anyone know what wents wrong here?

Did you setup the cronjob on your system? Or web-cron or just ajax calls? Which version of NC are you using? Platform?


I’ve a cron job running. The System is an actual Debian with PHP 5.6. NextCloud 10.0.2 stable is installed.

I have the same problem with rainloop app activ

And you use the encryption app?
