I have several forms on a clients site that use really simple captcha. They were working perfectly, but have recently stopped working (not sure when exactly). It appears that the problem is that the captcha images are not in the uploads folder, so you get a blank space where the captcha image should be, and have no way of doing the captcha, rendering the forms unusable.
I've also noticed that the client has used up all their server space, and thought this might be stopping the captcha images from being created. I removed a few obsolete images from the uploads folder to free up a little space, but the problem persists. Any advice would be very welcome!
Thanks
