Hi all,
I really tried to fix this myself but I wasted too much time on this already.
My wordpress contact form plugin doesn't work. I started with CF7, coudn't figure it out, decided to try another one (Fast Secure Contact Form) and it's all the same.
Double-checked all the simple things. Turned off everything else (all other plugins). No go.
Pastebin from the "test" function here.
Thanks in advance.
