Hi John,
What you have is absolutely normal, because data files aren't processed,
so it contain "special words" (Cumulus webtags) that need to be transformed
to weather data by Cumulus.
In php, data and pages are separated, so you need to process only 2 files:
wt_data_inc.php and
wt_month_inc.php. All pages need these files
to "fill the holes", where weather data is needed.
See step-by-step instructions to use it, in particular
Cumulus configuration.
So, hope you some fun with php learnings... knowledge often come
when something wrong occur!
Regards,
Jacques
