Thank you for writing in, you can convert your X to PRO license for free, if you purchased that license prior to the release of PRO which is APRIL 2017. Read more about X To Pro Conversion here.
You’re referring to the plugins (extension) that come with the Theme right? Yes, it has a separate update but it will come from us. If you have validated your Theme and you can not update any of the extensions then that means either you have an outdated theme/cornerstone, and/or your extension itself is outdated.
If you have an outdated theme then you need to update it manually. You can follow the Manual X Update Via FTP provided here, you can download the theme installer (.zip file) from the APEX dashboard.
After a successful update navigate to Plugins panel, deactivate and delete the Cornerstone. Then navigate immediately to X > Validation, X will automatically re-install the Cornerstone version that is bundled with it. Then you can now re-validate your Theme.
To update the Extensions to the version that is supported by the theme:
- Ensure your theme is validated so Extensions can be installed automatically
- Deactivate and delete the extensions, from the plugins panel.
- On the X > Validation > Extensions locate and install the extensions that you need.
- Visit "Plugins" panel in your Dashboard to activate the newly installed version.
Because all of the plugin settings are stored in the database, and because version 2.x will migrate settings from older versions, its safe to use this method of deleting the previous version. But always keep a backup of your entire site just to be safe.
Remember to clear all caches (plugin, server-side, CDN, and browser’s cache) after updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
Hope that shed some lights,
