Hi David,
You have made a pretty good start, but you only sent layout files!
At step 2 in template installation instructions, you have to send all
"internet" folder content to your website and it seems to be done ok!
But, you have also to copy all files in the "web" folder into local path
"C:\Cumulus\web" (Recommended Cumulus path). That will replace
Cumulus standard template, by Sunny Weather template, but Cumulus
will think that this is its original template, so in Cumulus, let the option
for "standard template" ticked on page Configuration --> Internet --> Files menu.
In Sunny Weather, all standard option for template files have to stay the same.
So these option have to stay ticked! (Standard template and Include standard graph)
En espérant t'avoir aidé un peu
Cordialement,
Jacques
