    I’ve downloaded the latest WP v5.4.2 and install Contempo plugin v.2.7.0, this is the error I’ve got. It says “The plugin does not have a valid header.” However, the plugin seems to activate again after I click “activate” link. Is there any fix that I’m not aware of?
    This is the screenshot of the error and the URL at that moment.
