Hi there,

Which line is line 15 of single.php?

Got it :]

There is one line of script in admin-ajax.php after my own ajax_action that says: die('0');
The solution is to add die() to the end of your own ajax function, so you die the script before die('0') :]

function secretnameofmyawesomeplugin_js(){
	if(isset($_POST['url']) && !empty($_POST['url'])){
		echo 'ok';
	} else {
		echo 'false';
	}
}
die()

Thanks for your comment willkemp, but unfortunately there are no relevant errors in the logs.

If I remove the add_option function and the update check, the error is gone. So I think something is wrong with add_option('wp_poll_db_version', $wp_poll_db_version);

I’ll post the whole script again:

<?php
global $wp_poll_db_version;
$wp_poll_db_version = '0.1';

function my_own_poll_installation(){
	global $wp_poll_db_version;
	global $wpdb;

	$table_name = $wpdb->prefix . 'poll_engine';
	if($wpdb->get_var("SHOW TABLES LIKE '" . $table_name . "'") != $table_name){
		$sql = "CREATE TABLE " . $table_name . " (
			id mediumint(9) NOT NULL AUTO_INCREMENT,
			time bigint(11) DEFAULT '0' NOT NULL,
			name tinytext NOT NULL,
			text text NOT NULL,
			url VARCHAR(55) NOT NULL,
			UNIQUE KEY id (id)
		);";
		require_once(ABSPATH . 'wp-admin/include/upgrade.php');
		dbDelta($sql);

		$welcome_name = "Admin";
		$welcome_text = "Congratulations, you just completed the installation!";

		$insert = "INSERT INTO " . $table_name .
			" (time, name, text) " .
			"VALUES ('" . time() . "','" . $wpdb->escape($welcome_name) . "','" . $wpdb->escape($welcome_text) . "')";
		$results = $wpdb->query( $insert );
//add_option('wp_poll_db_version', $wp_poll_db_version);
	}

/*$installed_ver = get_option( "wp_poll_db_version" );
if( $installed_ver != $wp_poll_db_version ) {
	$sql = "CREATE TABLE " . $table_name . " (
	id mediumint(9) NOT NULL AUTO_INCREMENT,
	time bigint(11) DEFAULT '0' NOT NULL,
	name tinytext NOT NULL,
	text text NOT NULL,
	url VARCHAR(55) NOT NULL,
	UNIQUE KEY id (id)
	);";
	require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
	dbDelta($sql);

	update_option( "wp_poll_db_version", $wp_poll_db_version );
}*/

}

function wp_poll_menu(){
	add_menu_page('WP Poll Engine', 'Poll Settings', 8, 'poll_settings', 'wp_poll_page');
	add_submenu_page('poll_settings', 'Subpage for Poll Settings', 'Subpage', 8, 'poll_settings_sub', 'wp_poll_subpage');
}

function wp_poll_page() {
	echo '<h2>Title</h2>';
}

function wp_poll_subpage(){
	echo '<h2>Subpage</h2>';
}

register_activation_hook(__FILE__, 'my_own_poll_installation');
add_action('admin_menu', 'wp_poll_menu');
?>

Hey Matt,

Maybe the register_activation_hook function is bugged, because changing the name of my installation function makes no sense. I’m absolutely sure there is no function called my_own_poll_installation_function() ??

As I said before, when I remove the line containing the register_activation_hook, there is no error.

Whoops, I marked the topic as resolved when I posted it ?? So, it is not resolved!

If I remove the line with the register_activation_hook function there is no error… But I want to use that function anyway.

Sorry, I need to post something more:
Above is the sourcecode of the admin area.

And by the way, I made this theme myself…

Well, it starts with a h3 wich isn’t closed. Then the whole sheet is displayed again and closes a p tag, wich isn’t opened…

Someone?

Thanks ??
