Thanks for the quick reply.
Still, I find it weird that captcha works with version 3.1.6.3 on a server with safe_mode but suddenly stops working with the latest update.
Hi! I’m experiencing the same issue.
On the website with WordPress 3.5.1 and FSCF 3.1.8.1, the captcha images fail to appear due to “Cannot modify header information” warnings.
However, on the other website that’s still on WordPress 3.5 with FSCF 3.1.6.3, the captcha images are fine. Both sites use the same theme and plugins.
Another possible factor is that my production server runs php 5.2 with safe_mode enabled (not something I have control over, unfortunately).
I disabled captcha for now but would prefer having them.
Any ideas what I could do to make captcha work?
