So far the simplest way to update the Helpie Kb plugin is to use the envato-update-plugins plugin. This plugin will check your envato ( codecanyon / themeforest ) purchases and show updates in your plugins page.
Note: It might take some time to show new updates. If you don’t see an update. Wait 15 – 20mins and do refresh a couple of times. The latency is because some servers only check other domains with a wait interval.
Another way to update the plugin is to delete the old Helpie plugin and upload the new version. This will not delete any of your data.
