No, the login is supposed to be handled through an API to another system.
So the user just logs in to the WP site with the credentials from the other site.
seemed to be a host problem. Works between sites on the same host.
I have the same problem.
The images are generated correctly in the wpcf7_captcha folder.
The link in the form is correct.
All folders are read/writeable
Still a broken image.
Anyone have a tip for another contact form with captcha? It seems this has a lot of problems for a lot of people.
