Problems with the plugin crash my page

  • Hi, today I have this error at my page :
    Warning: file_exists() expects parameter 1 to be a valid path, string given in /public_html/wp-includes/theme.php on line 400

    Warning: file_exists() expects parameter 1 to be a valid path, string given in public_html/wp-includes/theme.php on line 404

    Warning: Cannot modify header information – headers already sent by (output started at /wp-includes/theme.php:400) in /wp-content/plugins/wp-super-cache/wp-cache-phase2.php on line 1338

    How I can fix this?
    Thanks.

  • I don’t think it’s a problem with this plugin. This plugin just happened to send header information before this warning happened elsewhere.

    The lines in theme.php are in register_theme_directory() which this plugin doesn’t use so it’s probably the theme you’re using.
