Weather Display has reset itself

I’ve had to rebuild the data files to make data display correctly.

This has mostly worked but my daily report data has been stripped here and no longer shows all of January: http://217.199.187.197/otronics.co.uk/Weather/January2019.htm (it was showing the month so far).

How do I rebuild this page?

Also, how come some other reports are showing 2019 data for days that haven’t happened yet (see attached)? How do I correct this?
