I am a retired computer science teacher helping a friend with her web store and thought installing the Zen Cart 1.5 upgrade would be much easier than installing the original 1.3.9 since my knowledge of Zen Cart is much greater. It has turned into a nightmare.

A couple of years ago I gave up when installing version 1.3.9 and paid for someone to use Fantastico to install.

This time, I am determined to do it myself without Fantastico. I followed the upgrade instructions and did all file comparisons, etc. I set up several "stores" on my local server (Aztec) with absolute success: I first installed the 1.3.9 "store" downloaded from the remote server and worked from there. I upgraded to 1.5 following the upgrade instructions. It took forever to compare all files! All was a total success. The site is up and running 1.5 on my local server without a hitch.

I put together the successful file structure, updated the configure files and uploaded all files to the public_html directory on the remote Aztec server. I verified the requirements to be acceptable. I then attempted to launch zc_install via my web browser: http://www.sitename.com/zc_install. I received an "Internal Server Error" with a 404 file not found error.

I used an info.php file to test public_html access using http://www.sitename.com/public_html/info.php to reach it. No problem. I placed the file in the zc_install directory and attempted to reach it from my web browser: http://www.sitename.com/zc_install/info.php and received the same Internal Server Error.

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, [email protected] 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.

Apache Server at bmsshealth.com Port 80

I've checked permissions and think they are fine. I downloaded the zen cart files from the remote server, set up a "new" store with those files on my server here and had no problem upgrading this install. Works fine.

I contacted the tech for the remote server and he cannot find any problem at their end. He suggested I move to a store that had a reasonable install path. I'm not ready to do that. I like Zen Cart.

Error log files have provided no clues. Any help would be very much appreciated!
