Error – Plugin does not have a valid header

    Hi there
    I have two issues (maybe there is a correlation between)
    First: when I try to activate the plugin on the wordpress plugin page I get the message “The plugin does not have a valid header”. But when I activate it trough the installed plugins page there is no such message.

    second: I use the Advance Flip Box2 on a test page. Everything is working fine unless I activate the button option on the back of a flipbox. In that case the code is displayed in the flipbox and I get the error “failed to load resource: Error 404” wp-content/plugins/advanced-wpbakery-addons-formerly-visual-composer/assets/js/main.js?ver=1.0.0

    I have WPBakery Page Builder V 6.0.3 installed (came with Pofo theme) WordPress Version 5.2.2

    Any ideas? Many thanks for your help!
