Hi Glen,
I have sort of fixed but not fixed the problem.
I deleted all the files and installed 4, which works, and which is what I had previously, and the reason I wanted to upgrade was because images in the shop wouldn't show up.
Anyway, I have downloaded an upgrader cgi ( upgrade4kto50.cgi ) and when I follow the path I get this:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator,
webmaster@angelashes.com.au and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
