Decimus on "[Plugin: Fast Secure Contact Form] Newsletter Tab"

In the news Letter tab I keep getting a 500 - Inteal Server Error for the Constant Contact Newsletter Settings

Which folder should be 755? I cannot see anything in the log file.

Hi, what is your current folder and file permissions for your WordPress installation? Also check your server log files.

I can see nothing in the error log
