There are 4 steps in this method:
Step 1 - Make sure to backup your WordPress data
There are three different ways on how you can backup your WordPress data:
- The company where you host your webpage might have an automatic backup of the data already in place or allow you to do a manual one
- You can follow the WordPress instructions on the official website present at https://wordpress.org/support/article/wordpress-backups/
- You can use a third-party plugin such as BackWPup, UpdraftPlus, VaultPress (Jetpack Backup),BackupBuddy, Duplicator, or any other backup plugin available.
Step 2 - Deactivate and delete the old version
In the WordPress backend, go to the left menu "Plugins">"Installed Plugins", deactivate the plugin and delete it.
When deleting the plugin, if a warning popups up stating "Are you sure you wish to delete these files and data" proceed with the deletion.
Step 3 - Install and activate the new version
In the WordPress backend, go to the left menu "Plugins" > "Add New", click "Upload Plugin" and then select the downloaded new version plugin zip file, install and activate it as per the instructions in the User Guide Wordpress plugin
Step 4 - Clear WordPress Caches
If you have installed a WordPress js/css minify plugin or WordPress cache plugin for example, Autoptimize, W3 Total Cache, WP Rocket, WP Fastest Cache, WP Super Cache, empty all caches from the plugin.
Some web hosts, for example, GoDaddy, WPEngine, SiteGround, DreamHost, will also cache web files. You need to clear caches of the web hosting before testing. Please contact your web hosting provider and ask about how to clear caches.
