Few days back, one of our customer got back to us with an error code on their contact forms and registration forms. It was showing,
"Captcha plugin not set or not found. Please contact a site administrator"
The reason of the error was, the client did not switch off the captcha element from all the Joomla backend parameters. So, here are the list of options, which you need to switch off to get rid of the problem.
- Switch of Captcha Plugin from Plugin Manager
- Global Configuration > Default Captcha > None
- User Manager > Options > Default Captcha > None
