Fatal error on line 7

  • Hello,

    Are you still available to troubleshoot this plugin. It looks like it is exactly what I need but I can’t get it to work properly.

    Added template call to header.

    Installed plugin:

    “The plugin generated 255 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.”

    Added files for caching:

    Warning: file_put_contents() [function.file-put-contents]: Filename cannot be empty in /*/*/*/wp-content/plugins/manifest-builder/builder.php on line 206

    Visit site:

    Fatal error: Call to undefined function is_plugin_active() in /*/*/*/wp-content/plugins/manifest-builder/template_functions.php on line 7

    Any help to get this working would be AMAZING!

    Many thanks,

    Ali.

  • To fix fatal error on line 7, do this:
    open file ‘manifest-builder/template_functions.php’ in plugin editor and in the beggining of the file (just after line with <?php )
    enter “include_once( ABSPATH . ‘wp-admin/includes/plugin.php’ );”
    to look like this:

    <?php
include_once( ABSPATH . 'wp-admin/includes/plugin.php' );
if( ! function_exists('template_add_cache_manifest'))
{
	function template_add_cache_manifest()
	{
		if(is_plugin_active('manifest-builder'))
		{
			echo ' manifest="/cache.manifest"';
		}
	}
}
?>

    See Function Reference/is plugin active for details.

    Sorry, the file should be edited to this:

    <?php
if( ! function_exists('template_add_cache_manifest'))
{
	function template_add_cache_manifest()
	{
		echo ' manifest="/cache.manifest"';
	}
}
?>

    The function is_plugin_active is completely obsolete.
    But there is also another error, the plugin doesn’t update file cache.manifest nor creates it. It needs still to be repaired.
