 * Hi there,
 * I’m getting some weird PHP warnings with the **better-related-posts** plugin:
   [http://wordpress.org/extend/plugins/better-related/](http://wordpress.org/extend/plugins/better-related/)
   but only on **ONE particular post**.
 * I have been using the plugin without any problems for some months now, but all
   of sudden these warnings showed up on my single template:
 *     ```
       Warning: array_keys() [function.array-keys]: The first argument should be an array in /path-to/single.php on line 69
   
       Warning: array_slice() expects parameter 1 to be array, null given in /path-to/single.php on line 69
   
       Warning: array_search() [function.array-search]: Wrong datatype for second argument in /path-to/single.php on line 79
       ```
   
 * etc.
 * However, the related posts DO show up underneath these warnings with my custom
   query like this: [http://pastebin.com/JacTv2mZ](http://pastebin.com/JacTv2mZ)
   (
   line 69 from the warnings is line 2 in pastebin)
 * So I tried to pindown the problem and it seems it’s only occuring when there 
   is a **<object>** embedding in the post content like a soundcloud player in my
   case.
 * If I replace this original soundcloud embedcode with a shortcode (using [this plugin](http://wordpress.org/extend/plugins/soundcloud-shortcode/)):
   `[
   soundcloud params="player_type=tiny&color=006F9F" height="18"]http://soundcloud.
   com/trackname[/soundcloud]` the warnings are gone.
 * My guess is that this embeddingcode is being included in the MySQL Fulltext Search
   and causing problems, but I think it should be excluded?
 * Does anyone have similar problems or have a solution or workaround for my problem?
   Any help is appreciated!
 * Thank you!

 * Even with the new HTML5 soundcloud code using iframes the problem occurs.

 * No unfortunately not yet…
    I have a workaround though to check if **$scores**
   returns an array, if not I use the normal **the_related** [http://pastebin.com/TSCn9aRR](http://pastebin.com/TSCn9aRR)
 * I allready addressed the issue to the plugin author here:

 * Great. Thanks for the hint.
 * On my side I’ve found a sneakier way to “mask” the bug.
    I actually turned off
   the php errors display in the wp-config. SInce I was pushing the site into production
   I needed a quick solution. While it will makes the error log grow, it still make
   it a viable solution. + it still shows the other related while clearing the array
   slice error. if interested:
 *     ```
       error_reporting(0);
       @ini_set('display_errors', 0);
       ```
   
 * On my side the error was done using the integrated WP embed for youtube.
 * Cheers.
