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.

  • Ah of course, I've had this issue in asp.net sites. What threw us was it happened exactly on number 200 seemed like it must have been a limit. Commented Oct 29, 2015 at 3:29
