If you find some plugins does not work with your current wordpress version, you might want to downgrade your latest version to the old one.

Here how it works:

1. Backup your old site, expecially the wp-content , .htaccess and wp-configure.php
2. Download the older version from https://wordpress.org/download/release-archive/
3. Uzip the older version zip file, delete the wp-content folder
4.  DELETE all your current files in your current hosting wordpress folder:

– / except .htaccess and wp-config.php

– /wp-admin

– /wp-includes

Be sure to KEEP all of /wp-content

      5. Upload the older version to your hosting site wordpress folder

      6. Copy you /wp-content back.

Done. Now your site should be back to the older version now.
