A fresh installation. I can log in, but when I click for the second time on a menu item (another option perhaps), matomo throws me out with this error message:
An error occurred
Session must be started before any output has been sent to the browser; output started in /www/htdocs/w018af01/praesenz-web.de/matomo/core/bootstrap.php/32
Some time later I can log in again, but cannot do much (see above…)
Above the error message it says:
Warning : session_cache_limiter(): Cannot change cache limiter when session is active in /www/htdocs/w018af01/praesenz-web.de/matomo/core/bootstrap.php on line 32
Only one session is active at a time, this cannot be the cause.
I am happy to receive a solution, please for a code analphabet.
