Hi, this is complex to describe. I had to replace the WP preinstalled by my hosting provider because it had several problems. In a new installation of WP I created a new blog and import post from the old, to replace it after. In the new blog I installed cform 10.5.1 and I created a contact form for some pages. And also created a form for comments and enabled it. Everything worked fine.
When all was ready I replaced the old WP by the news.
Then the forms stopped functioning.
I checked cforms.js and add the new url, I clean firefox caché and restart it ,unsuccessfully. . No way.
I decided to remove and install Cform again, then the Contact Form works well, but in post appears in the contact form instead of the comments form.
