[Plugin: Contact Form 7] Suddenly a black captcha

Hello,

I am using WP 2.62 and the latest Contact Form 7 version, great software. Works well, until I found out, that the captcha field is now black on black. No chance to get something other out of it. I changed the colors (white on black or black on white) and reinstalled the plugin completely. But the captcha field stays black on black, ergo unvisible.

I have tested it in my other blogs, the same thing. Could not get Contact Form 7 to run anymore. 🙁

Any idea? I don’t like to switch to another plugin, because Contact Form 7 has done the job before the black captcha problem. Might be no big thing …?!

Thank you in advance.

Kind regards,
Frank
