I asked this question in the How-To & Troubleshooting forum two days ago, and have yet to receive a reply. Typically I don't post in more than one area, but I really need an answer on this one. So please forgive the double posting if you can.
I've upgraded to WP 3.0.1 and I'm having issues with the captcha image not displaying properly on the form (using latest plugins of Really Simple CAPTCHA & Contact Form 7). It shows a broken image, and when I view the source, it gives the correct URL to where the captcha image is stored. I have verified that it uses the upload path in settings->media, which is where it is located in the WP 3.0.1 admin dashboard, and that the folder permissions are set properly. I have also confirmed that both the gd library and freetype are compiled with my php install.
Are there any other conditions that may be causing this? Is the plugin simply not compatible with the current 3.x version of WordPress?
