Hi,
I am having the same problem. When I create a landing page from a template that I have either uploaded from wordpress admin page or through ftp directly into my server, I am not able to see the thumbnail and getting following error message.
Warning: include(D:\Program Files\Apache Software Foundation\Apache2.2\htdocs/wp-content/uploads/landing-pages/templates/D:\Program Files\Apache Software Foundation\Apache2.2\htdocs\wp-content\plugins\landing-pages\templates\clean-and-classy/index.php): failed to open stream: Invalid argument in D:\Program Files\Apache Software Foundation\Apache2.2\htdocs\wp-includes\template-loader.php on line 47 Warning: include(): Failed opening ‘D:\Program Files\Apache Software Foundation\Apache2.2\htdocs/wp-content/uploads/landing-pages/templates/D:\Program Files\Apache Software Foundation\Apache2.2\htdocs\wp-content\plugins\landing-pages\templates\clean-and-classy/index.php’ for inclusion (include_path=’.;C:\php\pear’) in D:\Program Files\Apache Software Foundation\Apache2.2\htdocs\wp-includes\template-loader.php on line 47
