Edit: This manual is no longer current, because the patch no longer exists in the Patch Tester.
Hi,
1.) Complete backup your site
2.) download this file:
https://github.com/joomla-extensions/pa ... tester.zip
3.) Install it in Joomla! backend --> Extensions --> Manage --> Install
4.) Go to backend --> Components --> Joomla! Patch Tester
5.) Press 'Fetch Data' button
6.) Seek Pull ID 19512 Revert routing changes in 3.8.4
7.) Press blue 'Apply Patch' button
8.) Check in frontend if pagination works again (Normally you need to delete the Browser cache before)
9.) If pagination is ok, uninstall the patchtester. Go to: backend --> Extensions --> Manage --> Manage --> Search Tools --> Select Type --> Component --> Joomla! Patch Tester --> Uninstall
Kind regards,
Benno
