More information about the problem:
- New pages with all new content have no problem. They can be saved etc.
- If you save a block from an old page that has a problem, and import it into a new page, the new page won't save.
- New pages appear to have detailed "parent" information that is missing in the old pages that won't save.
If you look at the data in the database, the text data for old pages that won't save end like this: "parent":false}]
If you look at the data in the database for new pages, there is detailed "parent" informatioon present.
I don't know if this is relevant or not, but I hope this information will be useful in locating the source of the problem. Our website has MANY pages and we can't rebuild all of them. We need to be able to use the existing pages. Can you plesae help us find the solution for this?
