After trying loads of things suggested throughout the forums, I decided to learn mod_rewrites. I got round the issue of:
“https://www.thesupermelon.com/trends/page/2/”
instead of
“https://www.thesupermelon.com/category/trends/page/2/”
By adding the following into my .htaccess file:
RewriteCond $1 ^(news/page) [NC]
RewriteRule ^(.*)$ /index.php/category/$1 [L]
This goes immediately after the “RewriteBase /” line.
In the lines above, you’ll need to change “news” for whatever your category is called. In blupixelz example, it would be “trends”
So my entire .htaccess file looks like this:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond $1 ^(news/page) [NC]
RewriteRule ^(.*)$ /index.php/category/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
