    When trying to install & activate through WP admin, I get the following message:

    The plugin does not have a valid header.

    Hi, what version of WP are you using?

    The plugin header should match the expected format -- I've never seen a problem with it before.

    I think what's happening is that something is causing a conflict, which causes either my plugin or another plugin to print an error message (or just break), which WP isn't able to interpret, thus giving you the misleading "invalid header" message.

    What other plugins are you using? Have you tried turning off all other plugins besides Forms 3rdparty?

    I think it might have had something to do with the error indicated by this post: http://wordpress.org/support/topic/error-on-install-6

    Please try v1.4.3 and let me know if the issue is resolved.

    actual problem may have been leftover hidden field plugin -- I removed the file entirely in v1.4.7
