 * I’m tearing my hair out here… specs:
    WP 3.9 / Graphene 1.9.2 [http://www.greatfallsmodelrrclub.org](http://www.greatfallsmodelrrclub.org)
 * Exact error as it appears:
    Warning: preg_split() expects parameter 2 to be string,
   array given in /homepages/38/d92370548/htdocs/greatfallsmodelrrclub.org/wp-includes/
   formatting.php on line 155
 * Warning: Invalid argument supplied for foreach() in /homepages/38/d92370548/htdocs/
   greatfallsmodelrrclub.org/wp-includes/formatting.php on line 157
 * Warning: implode() [function.implode]: Invalid arguments passed in /homepages/
   38/d92370548/htdocs/greatfallsmodelrrclub.org/wp-includes/formatting.php on line
   186
 * Steps to resolve:
    Disabled all plugins – No effect Changed theme to 2014 (with
   and without plugins active) – No effect Uploaded fresh copy of /wp-includes folder–
   No effect
 * Forum and internet searches turn up nothing… Any clue where to go from here?

 * Try re-uploading all files & folders – **except** the root wp-config.php & .htaccess
   files and the wp-content folder – from a **fresh** download of WordPress. Make
   sure that you delete the old copies of files & folder before uploading the new
   ones.

 * This is in the wptexturize() function and it looks like a piece of dodgy text
   is being passed to that function.
 * In fact, your error is that it’s an array() instead of a string. The theme here
   is showing the error in what appears to be a “description” field.
 * Go and look at the tag line of your site and ensure there is a proper string 
   in there for the site description.

 * Well now I fell like a complete idiot and utter n00b… the description line in
   the General Settings had the text “Array” as the description. Removed the text
   and voila! Huge thanks to Paul G.!
