The upcoming release of T(-) Countdown Control will include a number of changes that warrant a quick ‘pre-flight’ check before the plugin is updated. Before updating to version 1.6.0 or newer, please take a moment and check the following items to ensure the update will not cause a conflict with outdated themes or plugins on your site.
The first major difference that version 1.6.0 brings with it revolves around Meta Box by Tran Ngoc Tuan Anh. Meta Box is a very powerful plugin that many themes and plugins use to manage meta box and custom fields in WordPress. The recommended method of including the Meta Box plugin in themes/plugins has changed, and T(-) Countdown Control v1.6.0 uses this new recommended method.
However, this new method of loading the standard Meta-Box plugin might have conflicts with older themes and plugins that force-include their own ‘flavor’ of Meta-Box. Therefore we highly recommend that you check that your WordPress setup is able to install and activate the Meta-Box plugin before upgrading to version 1.6.0 or newer. Meta-Box is available directly from the WordPress Plugin Repository at: https://wordpress.org/plugins/meta-box/
As of version 1.6.0, the plugin registration and update functions have been replaced with our new licensing system. The plugin must now be registered using a valid licence key to continue to receive plugin updates and support. Licence keys may be viewed and managed at the Plugin Oven by logging into your account. Be sure you have secured your licence key before updating to version 1.6.0 or newer.
