I guess there is indeed no easy solution for this one..

That is correct, the only eventual links between Topic and Source are the posts themselves.

My bad, I didn’t add the “wp-blog-header.php” file..

require('./wp-blog-header.php');

require_once( ABSPATH . WPINC . '/registration.php');
require_once( ABSPATH . WPINC . '/user.php');

Indeed, here’s the solution on the multisite forum in case someone has the same problem:

Thanks everyone, just in case someone has the same problems, here’s the ht access code that solved it all:

RewriteEngine On
RewriteBase /

#begin WordPress
#uploaded files
RewriteRule ^(.*/)?files/$ index.php [L]
RewriteCond %{REQUEST_URI} !.*wp-content/plugins.*
RewriteRule ^(.*/)?files/(.*) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteCond %{REQUEST_URI} ^.*/wp-admin$
RewriteRule ^(.+)$ $1/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . - [L]
RewriteRule  ^([_0-9a-zA-Z-]+/)?(wp-.*) $2 [L]
RewriteRule  ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

<IfModule mod_security.c>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>
#end WordPress

but how is it possible that the links to the articles still work if there’s no htaccess file, is that possible?

That might be the funny thing, I can’t see the .htaccess file in the root folder (and it’s not because of my ftp client, because I can see them on other servers). I don’t know if it’s because there isn’t one, or if this specific server doesn’t allow me to see it?

Is there a way to get the code of the htaccess as it should be?

Thanks!

Didn’t find any upload path input in the Settings/Media, but found one in Super Aadmin/Sites/Myblog/Site options and it’s:

Upload Path = wp-content/blogs.dir/1/files
(1 being the id of this specific blog)

A few lines below there’s another field called “Upload url path” which is empty, does it need a specific value?

Nevermind, I updated the “Dashboard Site” field in the Super Admin > Option panel and it all went back to normal… no idea why, but at least it works

Well, I even tried to re-install worpdress using the “re-install automatically” functionality, but it didn’t change anything, the login screen still appears no matter what I do..

Is there a way to reset the database of this particular blog without crashing the other blogs hosted on the same install?

Edit: Interesting, the login page automatically wants to redirect me to the admin panel, when I go on my blog’s url here’s where he redirects me to: wp-login.php?redirect_to=https://insights.rbcdexia.com/wp-admin/&reauth=1
And when I’m logged as admin and try to access my blog, I got redirected to the admin panel..

I just tried, doesn’t look like it did any difference.
Thanks for trying to help!
