An unknown error has occurred

Hello !

this error has been driving me crazy since a week.

I have this error when I upload a file exactly named ‘readme.txt’ in Nextcloud (‘readme 2.txt’ upload fine).
I didn’t see anything in nextcloud.log and apache log.

I’m not sure this error is due to nextcloud, but if anyone has an idea…
Nextcloud version 19.0.3:

do you have ransomware-protection app enabled? would you like to check if uploading of readme is allowed?

Thanks for your suggestion.

Try a clean install: same error.

Finally I find an error in Plesk:

2020-09-19 15:04:51 Error 86.xxx.yyy.zzz 403 PUT [/nextcloud/remote.php/webdav/Documents/readme.txt](https://212.xxx.yyyy.zzz:8443/smb/file-manager/code-editor?currentDir=%2Fhttpdocs%2Fnextcloud%2Fremote.php%2Fwebdav%2FDocuments&subscriptionId=2&file=readme.txt&redirect=%2Fsmb%2Flog-file%2Fbrowser%2Fid%2F2)HTTP/2.0 146 Accès SSL/TLS Nginx

I found

location ~* "(?:wp-config\.bak|\.wp-config\.php\.swp|(?:readme|license|changelog|-config|-sample)\.(?:php|md|txt|htm|html))" {
        return 403;
}

in /var/www/vhosts/system/domain.fr/conf/nginx.conf

How to exclude readme from this rule ?

Maybe this links are interesting:


https://nginx.org/en/docs/http/ngx_http_core_module.html#location

Was Wordpress installed before?

I would try to simply remove “readme|” or the whole rule… But on your own risk :slight_smile:

Many thanks zentrix !!

I had to uncheck Block access to sensitive files in Plesk Wordpress Toolkit security

Yes Wordpress was installed before.
I try to remove "readme|” from the rule, but the rule is recreated automatically.

Edit:
Finally I add the Block access to sensitive files rules (but without "readme|”) in Apache/nginx settings in Plesk.
