Silverstripe Version: 4.6.1
What could cause this error: [Emergency] Uncaught LogicException: Cookie can’t be set. The site started outputting content at line 419 in public_html/vendor/silverstripe/framework/src/Control/HTTPResponse.php?
The website ran without any issues for a while and out of a sudden there is a server error. The hosting company claims they haven’t changed anything, but nobody touched the website (neither files changed nor admin area) for a few weeks.
Has anybody any idea what could cause this?
Thanks a lot.
