I wonder if anyone can help as I have a very strange problem which is doing my head in.
I have installed Contact Form 7 and Really Simple Captcha. I have confirmed the upload folder is correct and writable. I have confirmed that the captcha code is correct, referencing the same challenge and response and even tried playing around with the settings to change the presentation and font colour - but - each and every time the image is blank.
Every time I visit the contact page a new file is being created and this file is consistent with the image in the page. You can even right click and save the PNG image but the image is blank.
I have confirmed that I have freetype and GD installed and updated them to make sure they are the correct version and also installed the latest versions of contact form 7 and really simple captcha.
I have also spent the last two hours searching forums for anyone having the same problem, but I just can't crack it, I'm stuck.
Has anyone had a similar problem and were they able to resolve it?
Your help is appreciated.
