[Plugin: Advanced Permalinks] Error by going to page 2,3,4 etc.

I Have the same problem. please help me.

Are you using a cache plugin?

They sometimes fiddle with permalinks.

I had the same issue with this plugin. I thought it was only this plugin that didn’t work.

I downloaded the Simple 301 redirection plugin for my site and the problem still persisted with the pagination. So I did some googling and found this plugin:

https://www.htmlremix.com/projects/category-pagination-wordpress-plugin

I downloaded that plugin and installed it, and everything works fine now!

I think if you are using Advanced Permalinks, this pagination fix plugin should work as well! If not, then just use Simple 301 Redirection plugin with the pagination fix.
