The long answer is: Every web page on your website that contains weather information provided by tags from WeatherCat has to be processed by WeatherCat on its own!
Reinhard, I didn't know that. Because I am successfully accessing my banner and my steel series gauges in this manner, I assumed that I could also access data via a tag. Will it work if I use the
WeatherCat | Preferences | Custom Web | Additional Files option to upload the statistics_upload.html directly to the page? I am asking rather than trying it to see because you have to jump through big hoops to upload anywhere other than the standard uploads directory in WordPress.
Try treating the statistics as code and use the <code></code> tags. There are examples on the webpage above. It should allow WordPress to display WeatherCat statistics correctly.
Thanks for the suggestion Edouard. I am still working to wrap my head around this.
