# PHP Error "Illegal string offset 'file'

 * I installed the Pro Version of WordPress Thumbnail Slider on [http://www.beautymay.de](http://www.beautymay.de)
 * The slider works perfectly fine, however, every time a new article or page is
   published on that domain, a PHP Error occurs:
 *     ```
       Warning: Illegal string offset 'file' in .../wp-content/plugins/images-thumbnail-sliderv1/wordpress-thumbnail-slider.php on line 2223
   
       Warning: Illegal string offset 'file' in .../wp-content/plugins/images-thumbnail-sliderv1/wordpress-thumbnail-slider.php on line 2223
   
       Warning: Cannot modify header information - headers already sent by (output started at .../wp-content/plugins/images-thumbnail-sliderv1/wordpress-thumbnail-slider.php:2223) in .../wp-admin/post.php on line 222

       ```
   
 * This is the line in question on the Plugin-Code:
 * `$fileName=$photoMeta['file'];`
 * Pages and Posts are published correctly, however, this is a bit annoying.
 * I disabled all other plugins installed however the error still occured.
 * Any idea how to avoid these error messages?
 * Regards
    Michaela
