A common problem I’ve noticed with phpLD (php link directory) installations is Captcha not working properly. On these sites you will be able to complete all of the link information, but when verifying that you are human using Captcha, you can only enter a portion of the Captcha code that you are given. You are therefore unable to submit the link, because you will always receive a Captcha error. Often the Captcha code contains six (6) characters, but the Captcha field only allows you to input five (5) characters maximum. You would think that these Webmasters would notice the lack of link submissions.
The problem is due to the use of a third party template that has the maximum characters for the Captcha input field set too low. To resolve the problem, simply open templates/submit.tpl and find the code for the Captcha field. It will be something like: input type=”text” name=”CAPTCHA” value=”" size=”10″ maxlength=”5″ class=”input.” Just change the maxlength to as many characters as you need to hold the Captcha numbers that are being generated.
