I've a website with your gustebook running for about a year now and all of a sudden new guestbook entries are not showing up in the overview. I deactivated all antispam-countermeasures and I get a confirmation ("thanks for adding your entry", but then in Dutch) that my entry was succesful. But no result on the guestbookpage. Last entry was about 5 weeks ago, since then I didn't change anything to the website (themes/plugins).
Do you have any clue where to look at to solve this issue?
Thanks, kind regards,
