 * Hi there,
 * I’m helping a friend with his website and installed Polylang today (as he wants
   a bilingual website) – everything seems to be working fine except that I see 
   this message on the homepage (in the header area):
 * Warning: array_merge() [function.array-merge]: Argument #1 is not an array in/
   home/www/054b46091002c417fa925d2f2fb14f9c/web/wp-content/plugins/polylang/include/
   plugins-compat.php on line 75
 * I have looked at similar threads, but the warnings are slightly different so 
   I’m not sure how to go about fixing this one…
 * Any help would be greatly appreciated!
 * Thank you!
