WP Fast Cache
Failed to Open Stream and Cannot Modify Header (1 post)

    I had to deactivate this plugin due to an error/warning I get every time I try to edit a page/post in the admin (after hitting update and the file post.php is trying to reload). Funny thing is the changes are made. If I navigate to the page preview in a separate window, the changes are there, just the reloading of the page after editing is what causes the errors.

    I only have a theme, Tripod, and Revolution Slider, and Ultimate Maintenance Mode plugins installed/activated.

    Errors are:

    Warning: file_get_contents(http://sampleproperties.com/about-us/) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.1 503 Service Temporarily Unavailable in /home3/builder1/public_html/wp-content/plugins/wp-fast-cache/wp-fast-cache.php on line 621

    Warning: Cannot modify header information - headers already sent by (output started at /home3/builder1/public_html/wp-content/plugins/wp-fast-cache/wp-fast-cache.php:621) in /home3/builder1/public_html/wp-admin/post.php on line 235

    ....

    Host is hostgator, non-Win server.

    If anyone could help me get rid of those errors so I can reactivate and use this plugin, that'd be awesome.

    Thanks!
