The CAPTCHA is not working and I cannot login at my login page
This failure could have been caused by another plugin conflict with this one. If you use CAPTCHA on the login form and ever get locked out due to CAPTCHA is broken, here is how to get back in: FTP to your WordPress directory /wp-content/plugins/ Delete this folder:
This manually removes the plugin so you should be able to login again.
If it is not working for you, you must test for a plugin conflict.
Here is how to troubleshoot which plugin is conflicting:
Look on the Admin – Plugins – menu.
Temporarily deactivate (not uninstall) all your other plugins. Leave this one still activated.
Does it work now? If yes, Activate the other plugins one by one to determine which one conflicts. Which one was it?
If you still have trouble I need to know:
What is the error or problem?
What steps to reproduce the problem?
Which form is it doing that on? login, comment, registration, or lostpassword
What version of WordPress?
Do you have multi-site or BuddyPress installed?
Are any other plugins causing it? (deactivate all the others to see if the problem goes away)
