Paginated backend sites link to https://wp-admin

Hello everyone,

after migrating my site from http to https, I encounter a strange bug: All sites in the backend that are paginated (e.g. the Posts site if there are more than 20 posts) link their “next page”, “last page” pagination buttons to

https://wp-admin

Which makes me unable to access the second page without hacking it into the URL (which my less tech-savy users aren’t able to).

Does somebody know that problem or a fix?

I checked my .htaccess, it looks fine:

 Header always set Strict-Transport-Security "max-age=31536000"

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Also, I used the Search-Replace-DB tool to replace all http:// links with https:// where possible.

Other than that, I’m totally clueless.
