Working with a client, I noticed that the maintenance mode message shown when the store was in maintenance mode had misspelled the word "later" as "latter".
It was simple enough, I had to edit the English language file and edit the database stored English phrase.
- Fix the language file: includes/languages/en_US.xml
- Fix the stored database value: SELECT * FROM languages_definitions WHERE definition_value LIKE '%latter%';
- Clear the cache files in the admin. Start > Tools > Cache Control
