Failed to start the session because headers have already been sent by

I am facing a problem and I believe it’s with Vtiger integration.



I have tested before and it was working perfectly , but today, with a new campaing (with a new custom field ) I am getting erros:



This is that I can see at cron httpdocs/emm/app/console mautic:campaigns:trigger





Triggering scheduled events

43 total events(s) to be processed in batches of 100

0/43 [>---------------------------] 0%







[RuntimeException]

Failed to start the session because headers have already been sent by “/var/www/vhosts/doctorscopic.com/httpdocs/emm/app/bundles/EmailBundle/Model/EmailModel.php” at line 1164.





mautic:campaigns:trigger [-i|–campaign-id [CAMPAIGN-ID]] [-l|–batch-limit [BATCH-LIMIT]] [-m|–max-events [MAX-EVENTS]] [-f|–force] [-h|–help] [-q|–quiet] [-v|vv|vvv|–verbose] [-V|–version] [-n|–no-interaction] [-s|–shell] [-e|–env ENV]



Does anybody have an idea how to solve it? Is it related to Vtiger integration?



Thank you
