Sitemap Cron Error shop.php Line 315

[DaveBr]

Wonder if anybody can help here.

 

I'm trying to setup a cron job to generate the Google sitemap, but am running into this error using the CronTab module in v. 1.5.4.0

 

PHP

Notice: Undefined index: REQUEST_URI in /home/sites/'domain'/public_html/shop/classes/shop/Shop.

php

on line 315

 

The cron is obviously running fine, but there's an error during execution.

 

I've also tried the Google Sitemap module, but this returns "No input file specified." so feel I'm closer with Crontab
