The problem itself: I can't add events to calender.
I have an error in the installation:
php does not seem to be setup properly to query system environment variables. The test with getenv("PATH") only returns an empty response.
Please check the installation documentation for php configuration notes and the php configuration of your server, especially when using php-fpm.
when contacting the webhost for a solution, as I have no access to php, the response was:
We do not run php-fpm. Also, the environment variables are not exposed as the php process runs in a isolated area. YOu will need to work with owncloud on how to make the software work without the path variable.
is there a solution?
