I have a problem in Contact Form 7 in WordPress. I use the drop-down menu to create a list of countries and copy the shortcode into the form editor, and then when I save the form, I get a “connection reset” error in my browser and an Apache error. How can I fix this?
I am using localhost, XAMPP 1.8.3, WordPress 3.8.1, and Contact Form 7 version 3.7.
I had the same problem, most likely you’ve got segmentation fault of Apache on Windows.
Please try to increase the Apache stack size as it’s written here How do I increase the stack size for Apache running under Windows 7?
