    Hi,

    I’m using the latest WP version, after installing the plugin when clicking on activate I get an empty page (no menus or else) with the following warning: “The plugin does not have a valid header” and the plugin doesn’t get activated.

    Do you know what could be wrong?

    Thank you!
    Best Regards,

    Hi @jmlapam

    Why mark it as resolved if you didn’t even answer?

    Thank you!

    Hi, dunno. Maybe it’s an error in topics. I’ve re-tested it. It’s not due to the plugin. Perhaps, try deactivating other plugins or themes on a local installation.

    I have have the same problem, getting the error message “The plugin does not have a valid header.” when I click activate.

    New installation of WP.

    Additional information:

    I am duplicating an existing site in which this plugin has been working for a while.

    Same theme and plugins, this is the only plugin so far that as a problem.

    @egocefalo Did you find a solution?

    Hi @elr3000

    No, I didn’t, I just sticked to Yoast Seo’s integrated twitter cards.
