This is an excellent extension, but contains a few problems that need to be worked through. When I upgraded to beta 2, I was unable to see the output in component view (www.yourdomain.com/index.php?option=com_zweather), although it worked fine in the new module. The new location editor is an improvement, but if one accidentally "backs out" of a location without hitting save or cancel, the location locks and it is impossible to get back into it or to access it in any way. I am really looking forward to the cron job for version 6. I was unable to get it to work in version 5, so I am hoping to really work on the new version when it is out (I have godaddy server, which really makes this particular cron job difficult to implement). But again, this is a wonderful product.
With version 6, you now need to assign a menu item to Z Weather since it grabs the component settings from there. This method is different from version 5 but it now allows multiple component pages for different weather locations. Your URL will change with an appended "&Itemid=xx" text to reflect this.
For the record locking, you can try the "Global Check-In" menu option under the Joomla Administrator's Tools menu to release the lock. I will look into having a better solution for the next release. Thanks for the input.
