 * Hey there, great plugin by the way!
 * Here’s an error I’m getting while attempting to reach a post of a post type I
   created via CPT-onomies:
 * Warning: implode() expects at most 2 parameters, 5 given in […]public_html/wp-
   content/plugins/cpt-onomies/cpt-onomy.php on line 273
 * This error appears twice on the left half of my browser window, while my 404 
   page is on the right half.
 * Could it be because I have added extra metadata to the custom post type by adding
   meta boxes through functions.php?
 * I have also added custom fields to the custom post type via ACF Pro. Could it
   be that?
 * Any ideas on how to resolve?
 * I am using the latest version of WordPress and the Plugin, as well as X Theme
   by Themeco.
 * Thank you so much! I owe you a coffee!
    Chris

 * Looks like the parentheses are misplaced in lines 273 and 284. The last paren
   should be moved right after $eligible_post_types, like this:
 * `implode( "','", $eligible_post_types), CPT_ONOMIES_POSTMETA_KEY, $taxonomy, 
   $value );`

 * Thanks (@jcexygy). That fixed it for me, though I don’t know what error line 
   284 was causing.
