That's what I thought, but I wanted to be sure...

... which would mean that it would still run the page, but write nothing to the database. Unfortunately, the page isn't even finishing loading and getting to the FM query.

No idea how to tell if you've hit this limit, but I suspect it *should* throw a 500 error of some sort. You can use ini_get() to verify the values at runtime are set appropriately.

I'll give that a try...

No, it's a very simple page; as I've said, posting 700 characters works fine, posting 800 makes it fail every time, no matter whether the 800 chars are spread among separate input fields or in a single input field.

I tried it with plain text, just the digits 0-9 pasted 10 times for each 100 characters. No formatting, just plain text...

Haven't tried that, but I'll do so...
