First, thank you for forgiving my english which is not very good.
I installed Nextcloud 14.0.1 on an OVH web server. It worked in http. When I configured my web server in https, and that I call https://mysite.fr/nextcloud I had the configuration page. The configuration went well, the tables were created in my database, but when I call https://mysite.fr/nextcloud, I have a blank page. How do I handle this problem? Thanks for your help.
If you don’t see anything that stands out in the logs, feel free to post them here (or a pastebin).
The log file is located in /nextcloud/data/nextcloud.log … or you could also check /var/log/apache/ if nothing stands out to you in the nextcloud logs.
