 * Hi there,
 * I’m a big fan of your system. I use it on another site and tried for the first
   time to install it on wordpress with this plugin.
 * But once i installed the plugin i got a blank page with this error message (in
   French, so sorry for the translation) : “This plugin have no valid header”. And
   once back to the plugin page, your plugin is disabled.
 * Have you ever encounter this problem ?
 * Thanks, and i hope i’ll be able to install it on my Wp blog 😉

 * Hi henrilegrand,
 * Happy to help out a fan! 🙂
 * We have yet to encounter this problem with the Feelbacks on other sites. I quickly
   googled the error message “This plugin has no valid header” and it seems like
   one of the fixes is to download and install the plugin manually.
    Instructions:
   [https://codex.wordpress.org/Managing_Plugins#Manual_Plugin_Installation](https://codex.wordpress.org/Managing_Plugins#Manual_Plugin_Installation)
 * Another, potentially easier, fix would be to register for a code on our website
   which you can then add to your sites’ html ([http://www.vicomi.com/products/feelbacks/register](http://www.vicomi.com/products/feelbacks/register)).
 * If you are having trouble with either solutions please contact us at support[
   at]vicomi[dot]com for further assistance.
 * Best
