O.K., I installed the latest Anti-Robot 2.9 contrib. I see the gray text box and it does generate random text. Problem is that when I enter the exact same text as in the box it does not validate. I get " Invalid Validation Code" every time. Any ideas where to look?
Also, I had to use the validation_png_25.php(86kb). Is this correct? When using the validation_png.php (9kb) I would only get a box with red X and no text generation.
