But it also did work..
Please help..

What happens when you reset your permalinks to the default setting?

It gives;
https://www.skydance.nl/?cat=76&paged=4
And the next and previous links are working..

But as soon as i turn custom structure on again with;
/%category%/%postname%

It fails and gives a 404 error..

I know what the problem is;

When i delete the .htaccess i get this URL;

https://www.skydance.nl/category/nieuws2/page/2
And thisone works!!

But when i refresh the page i get;
https://www.skydance.nl/nieuws2/page/2

So the category before is gone, this one Doesnt work..
So just link to the good URL and your problem is solved!

Thanks!

Do you guys have specific showposts= in your query lines by chance?
