 * Hello,
 * I have a problem:
 * When I want to filter my posts by tags (It’s called ‘Merkmal’ on my site, the
   dropdown menu), there always appears this errors:
 *     ```
       Warning: strpos() expects parameter 1 to be string, array given in /www/htdocs/w0119b73/uhr-test.de/wp-includes/query.php on line 1950
   
       Warning: preg_split() expects parameter 2 to be string, array given in /www/htdocs/w0119b73/uhr-test.de/wp-includes/query.php on line 1951

       ```
   
 * I don’t know why and how I can fix it. Funnily enough the filtering works even
   with this warnings.
 * Here you can test it yourself and see the error: [http://www.uhr-test.de/typen/herrenuhren/](http://www.uhr-test.de/typen/herrenuhren/)
 * Hope somebody can help me. Thanks for your time, have a nice day!
 * Greetings, Malte
