My client did minor edits to a normal page, including the page title, which is what gets pulled into the menu. On update, the entire menu of the whole site froze - nothing appears in the dropdowns under any menu heading. When she set the status of the updated page to “closed” everything went back to normal - except the page of course is no longer there.
Notes:
1. The first thing I tried was changing the URL name, which she’d left the same. Did not fix the problem.
3. Double-checked the open and close dates - nothing amiss there.
2. Searched every line of code, can’t find anything wrong.
4. Published a new blank page from scratch and pasted the content into this, gave this a new name and URL name. Same problem - when submitted, entire menu goes blank.
5. Tried to duplicate the problem on the development site (she worked directly on the production site) but on the development site, no problem.
6. Emptied newly published page of all data but the word “blank” and took all punctuation marks out of the title. This may have been the problem - there were quotes and a colon in the title. The renamed page doesn’t destroy the menus.
