# Error while adding new category

 * Tag group plugin is excellent as it allows me to group the tags even when tags
   do not have hierarchy feature.
 * However, whenever I try to add a new category I get this following error:
 *     ```
       Warning: array_merge() [function.array-merge]: Argument #1 is not an array in /home/goleor/public_html/danapredict.com/wp-includes/taxonomy.php on line 2367
   
       Warning: Cannot modify header information - headers already sent by (output started at /home/goleor/public_html/danapredict.com/wp-includes/taxonomy.php:2367) in /home/goleor/public_html/danapredict.com/wp-includes/class-wp-ajax-response.php on line 129
       ```
   
 * And when I deactivate Tag Groups plugin, there is no error while adding category.
   So the problem seems to be some kind of conflicting codes in Tag Groups plugin.
 * You may please note that I have following settings for Tag Groups plugin:
 * Taxonomy – post-tag
    Theme – ui-darkness Use Jquery – checked Further options–
   Collapsible tags (checked)
 * And, this is how I am calling it in archives.php
 *     ```
       if ( function_exists( 'tag_groups_cloud' ) ) echo tag_groups_cloud( array( 'smallest' => '13','largest' => '13','amount'=>'99' ) );
       ```
   
 * Given these settings, Category taxonomy should not be affected because I am using
   post_tag for Tag Groups. I wonder why it is happening.
 * Can someone suggest how to fix the error while adding a new category?
 * Many thanks.

 * Could you please try version 0.8.1 if it fixes the warning?
