[Plugin: Contact Form 7] Suddenly a black captcha (3 posts)

    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,

    Do you use a hosting server? I doubt the image libraries of PHP on that server. Updating libraries sometimes cause sudden trouble.

    Yes, I have a webhoster. But there is no problem with the captcha, if I switch to PHP 4.x on this server.

    Might be something related with PHP 5.x and imaging. Any idea?
