I use Nextcloud 12.0.1 with PHP 7 / MySql and it used to work pretty fine… until it craches during an upload of an entire directory. There was some notification messages like “This folder doesn’t exist” and then “Internal Server Error”. I pressed “F5” and I get a white page. Now, every links to my nextcloud instance (contact / mail / calendar apps) displays a white page.
The nextcloud.log file doesn’t seem to be really usefull… there’s no line corresponding to my issue. The last line records an operation made couple of hours before the crash. I made few uploads just before it crashed.
What can I do ?
