You might encounter an error message like: "Plugin named 'yith-topbar-countdown' is corrupted."
This error can originate from either your current WordPress installation or the source WordPress installation where the file was created. In order to address this issue, delete the problematic plugin and retry the import process.
Initially, the system will detect a plugin issue and display a corresponding error on the user interface.
For instance, it might report that the plugin 'yith-topbar-countdown' is corrupted. If the plugin is deleted and the file is still found to be corrupted, the error message will change to the previously discussed file corruption error. In this case, you can proceed by deleting the corrupted file and attempting the import once more."
