Why is the content missing from the modules after reactivating the plugin?

The content is missing from the modules after reactivating plugins because when third-party plugins are deactivated, any pages that were saved with those plugins deactivated may not display their content properly when the plugins are reactivated.

This could result in missing content in the modules used on the page. To avoid this issue in the future, it is recommended to refrain from saving pages with third-party modules while the plugins are deactivated to prevent any loss of content or unexpected behavior.
