The fix for the built in captcha is simple, replace your ./include/class_captcha.php with the one below. This should work in v5.6 as well. Must have been an error in decoding.


I haven't tested as I do not have a copy installed as of now so just let me know if you have an issue.


Kind Regards.

Bump: The updated fix attached below, I also aded a fix for another captcha (when certain funcs arent available).

Also fixed a silly bug where the captcha could be bypassed.

Unfortunately, the code tag didnt format the code properly in my last post, sorry about that.
