How do I change the "Read More" text
OK, if you did it with code you probably edited settings.php and did something like:

$conf['locale_custom_strings_en'][''] = array(
  'Read More' =&gt; 'More information',
);


You would have to remove that line from the array.

There are a billion ways to do it via code, though, To be safe, you should search for the string "More Information" in all of the sites/ files to be safe.

If you didn't do it with code, there is a decent chance you used the String Overrides module, and did it via the UI.  If so, delete that entry.

If this is related to a view, then you should poke through the settings for that view (don't forget the master and all additional displays).  Look for a link field, and check the "Text to display" option.

If not, poke around the field settings for your content types, eg admin/structure/types/manage/page/fields, and see if you set it there.
