CAPTCHA not accepted

    I have the CAPTCHA setting enabled on my forms. Fortunately the letters area clear and easy to read, but the correct CAPTCHA codes are not always accepted. Even refreshing the page didn’t work. I had to navigate away from the form page and then back to it for the CAPTCHA code to be accepted in a recent attempt. When this situation happens, refreshing the image does not help.

    Has anyone else seen this? How can I resolve this so the CAPTCHAs are consistently accepted? Is there some synchronization problem? Please help!

    Thank you for the suggestion, mbrsolution. I have implemented the PHP sessions feature to see if that will help. In my case, the CAPTCHA isn’t Always marked as incorrect, which of course makes it hard to know if the problem is resolved.

    Sometimes a page cache plugin can interfere with the captcha.
    If you have a cache program like W3 Total Cache or related, be sure to add your form page to the “Never cache the following pages:” setting in the Page Cache section.
    I have a support page and a contact page with forms, so this is what I have in my W3 Total Cache setting:

    wp-.*\.php
index\.php
support
contact

    I have just added this info to the help page

    Thank for that idea, Mike Challis. I use WordFence for caching and will add exclusions for the form pages. I haven’t seen the intermittent CAPTCHA problem again since updating the PHP sessions setting, but I’ll add this as well.
