Matrix field not saving 200th entry We have a matrix field for weekly winners names in a company promotion. We've entered 199 so far, the 200th is not saving, it blanks out the fields and logs a validation error - cannot save because name is blank.

If we delete item 199 then we can add a new item, it then fails on item 200 again

Is this a known limit in craft matrix fields??
Take a look here, it sounds like you are hitting the max_input_vars limit. Strange things happen when you do.
