 * Hi,
 * Installing the latest version (4.3.13) through TGMPA or through WP dashboard 
   throws the following error upon activation:
 * Downloading installation package from [https://downloads.wordpress.org/plugin/redux-framework.4.3.13.zip…](https://downloads.wordpress.org/plugin/redux-framework.4.3.13.zip…)
   
   The authenticity of redux-framework.4.3.13.zip could not be verified as no signature
   was found. Unpacking the package… Installing the plugin… Plugin installed successfully.
   Plugin activation failed.
 * An error occurred while installing Redux Framework: **The plugin does not have
   a valid header.**.
 * Thanks.

 * ‘The plugin does not have a valid header’ error can occur when the folder structure
   of the plugin is incorrect. Perhaps try deleting the `redux-framework` folder
   from /wp-content/plugins/ and then install from Plugins > Add New, use the search
   bar to search for Redux Framework and choose Gutenberg Template and Pattern Library&
   Redux Framework. If you run into an issue activating, go to Plugins and try activating
   from that page.

 * Installed the plugin from Plugins > Add New and also shows the error ‘The plugin
   does not have a valid header.’ upon activation.
 * Yes, it can be activated from Plugins > Installed Plugins, but the problem is
   when you need it to activate automatically, so users with less experience don’t
   think the theme is broken because the theme options menu is not showing.
 * I believe the problem is that there are two plugin headers defined: “Template
   Library and Redux Framework” and “Extendify”. If I remove the Extendify header,
   the plugin can be activated without any errors.
 * Thanks.

    Never mind, A colleague figured it out. I’ll get it fixed ASAP.

 * I pushed an update to fix this. You may want to notify the theme author in case
   they need to update. Good luck!
