The server encountered an internal error or misconfiguration and was unable to complete your request.
Logging into my control panel, I go through the process to send out a newsletter. I have used the 'air mail' Template to date, which I had modified previously and saved it under a new name. The template has an image in it (train), which I would like to replace. Going to the 'image' icon in the template and clicking on it brings up a mini control panel for inserting a new image. Then, clicking on the 'browse your computer' option to find an image on my computer it brings up the error message noted above.
So, it seems as if the template is not speaking to some or other processing file?
