   Hi forum

   I have installed the latest versions of contact form 7 and really simple captcha.
   the problem i am getting is my .png images are just black boxes - not the white background black text boxes they should be, everything elese seems fine and i cant figure out why its not working, my isp says theres no prob with GD or freetype on the server also.

   the .php files have the generated four letters/numbers in them, its jsut that you cant see anything on the image files.

   any help would be much appreciated.

   Thanks

   Hi,

   I have the same problem.

   I first developed my site off line with Xampp. The letters/numbers were black on a white background. When I uploaded the site I noticed the black text boxes. I've solved it temporally by making the letters/numbers white.

   Should this problem be related to the MySQL client version? Who can help?

   Hi,

   I solved the problem with black .png images.

   I converted the sql-database to UTF-8 with Notepad++

   I had the same issue. Modifying the foreground color in really-simple-captcha.php worked. Change this array $this->fg = array( 0, 0, 0 ); to a different color/set of numbers.

   I'm having the same problem. If you follow the documentation:
   [captchac your-captcha size:s fg:#ffffff bg:#000000]

   the image colour works but the text colour doesn't change so it's white on white or black on black etc!

   Also tried editing the array in really-simple-captcha.php
   $this->fg = array( 0, 0, 0 );

   But still the text colour doesn't change making the captcha image unreadable

   Please can anyone help?
   Thanks
