[Plugin: WP Carousel] Two problems on version 0.5

About the second error, this is a problem with permissions, please, update to WP Carousel 0.5 and try to save changes. You’ll get an error message. That message will show the path to the file that WP Carousel is trying to load.

If the path is correct (to load the file wp-blog-header.php) check the permissions. This is a huge bug that has to be solved as soon as possible.

Thanks for report!

WP Carousel uses the following code to create the path to wp-blog-header.php:

$folder = str_replace('/update_db.php', '', $_SERVER['PHP_SELF']);
$folder_exploded = explode('/', $folder);
$folder_count = count($folder_exploded);
krsort($folder_exploded);
$folder_count--;
unset ($folder_exploded[$folder_count]);
$folder_count -= 2;
$folder_path = "";
$folder_temp = 0;
for ($folder_temp = 0; $folder_temp < $folder_count; $folder_temp++)
{
$folder_path .= '../';
}

if (!is_readable($folder_path . 'wp-blog-header.php'))
{
// ERROR THAT YOU GET
}

The default path to update_db.php is: WORDPRESS_ROOT/wp-content/plugins/wp-carousel, so if the path you get is ../../wp-blog-header.php, WP Carousel is trying to load the file WORDPRESS_ROOT/wp-content/wp-blog-header.php. That file does not exists. The path should be ../../../wp-blog-header.php.

Don’t worry, I’m trying to fix this bug. Meanwhile, WP Carousel 0.5.2 offers a different solution: saving the content without AJAX. You’ll see a link to save the content when you get the error, so click it and don’t worry.

Sorry for the inconvenience and thanks for report!
