Error AH01797: client denied by server configuration

Domains and Hosting
1

Hello everyone,

My domain name is : https://vincianewery.be/

And I use the offer : Kimsufi 2015

The host has a WordPress plugin installed, used since 2016 without any issue. For a few days/weeks it is in error.

I have the following problem, accessing the website will return a 500 error. Looking into the logs and I see this message AH01797: client denied by server configuration for all files (or AH01630: client denied by server configuration error, two codes, but same message).

I've checked the .htaccess file, it hasn't changed and here is the following content :

RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L]


I haven't updated anything. Nor PHP nor WordPress nor any plugins…

Any idea ?

Thanks
