From the comment of the core captcha add-on's file you may now that '8fy7u
' combination should appear if you passed the param '/?md5=O2RAD00=
' and if you have secret password zxDF5612
. But even if you change a secret password (which is a must-do
), it is nearly to impossible to have only zeros displayed. I could only suppose that there is some misconfiguration or error on your side which can't be determined without deep seeing of the code. You may refer for our paid support
, we charge just $6 for installing the Captcha add-on and in most cases your problem could be determined in minutes.
