 * Guys,
    need help.
 * Those are errors:
 * [https://mega.nz/#!iBA2hYDB!WayC-AWYO4PafNZ9f6kyoeaUicaYn-mWtJtMVillfDo](https://mega.nz/#!iBA2hYDB!WayC-AWYO4PafNZ9f6kyoeaUicaYn-mWtJtMVillfDo)
 * and this is code :
 *     ```
       $dropdown_cities = array_reduce( $cities, 'array_merge', array() );
       					sort( $dropdown_cities ) ;
       				}
   
       				foreach ( $dropdown_cities as $city_name ) {
       ```
   
 * What should I correct here?
 * THX!

 * Hi,
 * Unfortunately I can’t view the errors as that site is blocked where I am (and,
   indeed, you might find some people won’t follow links such as that as it may 
   lead anywhere!).
 * However, you say in your title that this is from a plugin? Have you tried the
   support forum for that plugin for assistance?
 * David.

 * Yes I have. No help, they said that will try…

 * No, that link isn’t accessible either. Can you just cut/paste them here?

 * Thanks, although I’ll need to know the missing bits – all those dots are hiding
   filenames that I need to know (I don’t know which plugin we’re talking about,
   for instance).

 * Have you changed your user ID? Only, I can’t see any request for help at the 
   plugin forum. Here is the one…
 * [https://wordpress.org/support/plugin/wc-city-select](https://wordpress.org/support/plugin/wc-city-select)
 * They appear to be pretty quick at their responses and, as it’s their code, I’m
   sure they’ll be be able to work out the cause far quicker than I could!

 * Hi,
 * I’ve found your conversation on GitHub and it looks as if the developer has pushed
   out a change to fix your issue…

 * Can you confirm this is resolved?
