Advanced guestbook

Hi, i have advanced guestbook on a website for your soccer team and my father should wrote a message there, he wrote his name, the mesages who was quite long and then he filled in the human verification field but the the guestbook said that something was wrong and the long messeges he had wrote was no gone. I have never have problems writing in the guestbook but he had tried two times to wrote long messages and it say that something is wrong, i have cheked the settings and it allows 1500 characters but that qiute a lot so i dont think he wrote more than that, anyone who have a clue what the problem could be?

Got a link?

Sorry, http://forum.billingsforsik.net
The site is in swedish.

Weird, I just tried and had no problems at all.

I have never had any problems eiter but my father has, why couldt it be so?

Do you know the exact error message he receives ?

It says something like one field is not correct filed or something like that but he has complete the fields name, message and human verification filed. There is no morte he had to fill in but yet he got an error message.

To be honest I'm lost. I know some later versions had a time limit but not 2.2. You are using my anti spam mod, are you using any other mods ?

I would suggest updating to 2.4.2.

Okey, thanks for your help, i should try updateing.
