Finally figured out what was wrong by looking at some other guest book sites. NOwhere could I find in the limited documentation that you have to copy the letters at the end of the frame into the box. Would be nice if there was an instructional message to copy the letters into the box.
I just installed AGB 2.4 had have the same problem in posting messages to the guest book. I used the admin function and set the word count in the general section to 150 words. Minimum 6, characters 1500, words 150. I still get the
"One of the input fields does not seem to be valid"
error message. How do I fix this?
