Few days ago, I was using a theme for one of my WordPress sites. A newer version of WP released and I upgraded it. Then I faced a problem. The pagination system was not working with new version of WP. So, I had to downgrade WP!
You may face this problem too! What should you do? Because, unlike upgrading, there is no option for downgrading your WordPress!
See, how did I downgrade WP-
1) You must know, which version of WP you were using. Go to this link and download that version. Link: http://wordpress.org/download/release-archive/
2) Extract (Unzip) that ZIP file in you computer. You’ll find a lot of files including folders named wp-admin, wp-contents and wp-includes. Copy wp-admin and wp-includes folders. See the image below:
3) Delete wp-admin and wp-includes folders from your server.
৪) Upload wp-admin and wp-includes folders to your server.
Hope, your problem will be solved. I followed this way and I was succeeded. Whole process is silly risky. So, be careful. I’ll not be liable for any damages. For additional security, you may back-up your old files.
