Uploaded file is too large message doesn't display

Do you have a correct message setting corresponding to “Uploaded file is too large” situation in the Contact Form 7’s form edit page?

Yep, my setting is the message for this situation. Have another type of setting for too large file?

Can you check PHP error logs?

Yep, this is the error log for yesterday: https://codepad.org/0LiMALhW

I meant check it for yourself. You’d better not make logs public. And, it is not error log, that’s access log.

Well, i finally check the error log, but nothing happend.

Is strange because is the only error with the form :/

ok, then try deactivating all other plugins and switching to the default theme. If it solves the problem, one of them is interfering.

I tried that yesterday, but the result is the same. The message doesn’t display.
