Not a power user here. I am using nextcloud as selfhosted on my web page and used it without trouble till a few days ago. Though I did not change anything, it does not synchronize files by “server replied: Method not allowed”. Tried to look for a solution on web but couldn’t find anything. Is this a very specific problem? What may be wrong?
Nextcloud version 15.0.7
Operating system and version: Debian Testing
Log says: You are using a fallback implementation of the intl extension. Installing the native one is highly recommended instead. at /home2/xxxxxxx/xxxxx/xxxx/3rdparty/patchwork/utf8/src/Patchwork/Utf8/Bootup/intl.php#18
Edit: Installed intl extension for php, still the same.
