 * Hi, suddenly, I think since updating to WordPress 4.7, I’m getting this error
   on blog posts:
    Warning: Illegal string offset ‘taxonomy’ in /home/xxx/mysite.
   com/wp-includes/taxonomy.php on line 1874
 * Warning: Illegal string offset ‘object_ids’ in /home/xxx/mysite.com/wp-includes/
   taxonomy.php on line 1875
 * Warning: array_pop() expects parameter 1 to be array, object given in /home/xxx/
   mysite.com/wp-content/plugins/carbon-breadcrumbs/core/Carbon_Breadcrumb_Trail_Setup.
   php on line 135
 * It appears before the breadcrumb. All other pages are fine.
    As I said, I think
   since 4.7, but I’m unsure, my site is still in development and I haven’t visited
   my blog posts for a while.
 * A brand new post adds an additional error:
    Catchable fatal error: Object of 
   class WP_Error could not be converted to string in /home/xxx/mysite.com/wp-content/
   plugins/carbon-breadcrumbs/core/Carbon_Breadcrumb_Item_Renderer.php on line 112

 * Went away. Some plugin incompatibility. Great Plugin!
