Weird Drupal Error (The character encoding of the HTML document was not declared) I have Drupal 7 with multiple taxonomies and recently for only one (the largest one) when I go to the following taxonomy page:

www.site.com/taxonomy/term/216746

all is fine.

Then when I click edit:

www.site.com/taxonomy/term/216746/edit

My screen goes blank and I see in the console that I get this error:


  The character encoding of the HTML document was not declared.  The
  document will render with garbled text in some browser
  configurations if the document contains characters from outside the
  US-ASCII range.  The character encoding of the page must to be
  declared in the document or in the transfer protocol.


This does not happen with any other taxonomy term and suggestions would be great. Also, I looked in the database and I notice any differences between the terms.
I turned on errors in the settings.php with ini_set('display_errors', 1); and I found it was a memory issue.  

I added ini_set('memory_limit', '500M'); to the settings.php file, and all works.
