Development version

If you want to run the most recent development version ( not on important live sites please..., unless I asked you to do so ) do the following:

• Go to the Plugins admin page.
• De-activate the plugin.
• Delete the plugin.
• Download the latest development version of the plugin
• On the Plugins -> Add New page click the button and upload wp-photo-album-plus.zip that you just downloaded.
• Activate the plugin

You can look at the header of the Photo Albums -> Settings Admin page, it lists the revision numbers: e.g:

Database revision: 7208. WP Charset: UTF-8. Current PHP version: 7.0.6. WPPA+ API Version: 7.2.08.004.

That's all, you will be sure you have the newest version.

If everything fails and you want to go back to the release version, de-activate, delete and re-install as if it is a new plugin. All settings, albums and photos will survive all your (de-)activations and deletions of the plugin. You can ignore the warning: "Are you sure you want to delete WP Photo Album Plus and its data?"
