I migrated my installation from Jessie (8.1) to Stretch (9.4; another machine), and everything seems to work fine, except for one thing:
When i try to create a self-signed certificate for a subdomain, it is rejected with an error and i receive an error mail:
- Version: 1.5.1
- Build: 20170908
- Nachrichtenpriorität : Error
- [188.8.131.52] Could not write in
- /var/www/imscp/gui/data/tmp/13-openssl.cnf0re5bK openssl temporary
- configuration file.
The mentioned folder has the same permission as on the old machine.
Any advice to address this problem?
