object not found

Hello Pete and crew,

Since a couple of weeks my/your guestbook stopped working

I get the following error:
Date:
Fatal error: Call to a member function showDate() on a non-object in /home/momak/domains/cattery-momak.com/public_html/list.php on line 98

I *think* it is referring to function showDate, but it can't find any.
I have no PHP knowledge, but i hope you could help me out

Greetings,
Stefan

Hello Stefan,

It looks like you may have a corrupt data file. Did you edit the data file manually? That is usually the main reason for the message you are receiving.

Thanks,
Pete

Hi Pete,

I did edited it manually: Styled it to my website and added a new field. It worked fine, but suddely it stopped. I'll send you a pm.

Greeting,
Stefan
