An issue was identified with a 3rd party library resulting in captcha’s failing in versions 6.0 and below. If you are actively using captcha’s, please download the hotfix, extract and upload the files to your Clientexec directory.
Alternatively, you can disable captcha until version 6.1 has been released which will include the fix by default. However, disabling and waiting for 6.1 to be released is not recommended.
If you experience any issues our support team remains on standby to assist you.
