If you are talking about a plugin you need to let us know the EXACT name of the plugin. There is more than one re-captcha plugin 🙂
Assuming you are talking about a plugin (and not hard coding) you can FTP into your site and rename the re-captcha plugin folder to temporarily disable it so that you can get back into your admin panel.
The plugin is “recaptcha login” and I got the same problem… any clue ?
You need to post on the plugin’s own sub-forum for help with a plugin:
http://wordpress.org/support/plugin/recaptcha-login
If you want to deactivate it, do as suggested above – use FTP to access the files on the server and rename that folder inside the plugins folder –
wp-content
plugins
recaptcha-login - RENAME or DELETE THIS FOLDER
No problem for accessing my dashboard, I just deleted the folder through ftp access, I did post in the sub-forum but the owner already did not reply a previous message 3 month ago, not sure is willing to help… was hoping someone use this plugin with success and may know what’s wrong…
Thanks
Ok, problem “solved” for me by using another plugin that does work : Easy Captcha Thanks
same as rely28 here, instead of “recapcha-login” i’ve switched to Easy Captcha and all works fine, thanks
