I did re-install it through : </p> <p>- Login to your dashboard<br /> - Go to Add New under the Plugins Menu (Plugins &gt; Add New)<br /> - Select Upload<br /> - Upload the 1.5 zip file<br /> - Install and activate </p> <p>But, I did this process one more time after seeing your comment .It didn't work. I see the same message :</p> <p>The plugin does not have a valid header.</p> <p>I use Version 3.1 of WordPress. </p> <p>Welcome to your comment. </p> <p>Thanks<br /> Bob </p> https://legacy.forums.gravityhelp.com/topic/the-plugin-does-not-have-a-valid-header-2#post-21492 Fri, 25 Mar 2011 12:04:45 +0000 Carl Hancock 21492@https://legacy.forums.gravityhelp.com/ <p>It sounds like something went wrong during the install, or however you uploaded the plugin files. This can happen when installing via FTP, etc. an extra space gets added.</p> <p>Uninstall Gravity Forms and delete it completely from your web server. Then try re-installing.</p> <p>- Login to your dashboard<br /> - Go to Add New under the Plugins Menu (Plugins &gt; Add New)<br /> - Select Upload<br /> - Upload the 1.5 zip file<br /> - Install and activate </p> https://legacy.forums.gravityhelp.com/topic/the-plugin-does-not-have-a-valid-header-2#post-21469 Fri, 25 Mar 2011 10:23:45 +0000 Bob 21469@https://legacy.forums.gravityhelp.com/ <p>Hi Guys, </p> <p>I just bought the Plug in, I installed it successfully.
