Meteotemplate Forum

Hello, I have the template working. There are a few things that I don't understand or that are wrong. I have been messing with adding data myself. That turned out to be a stupid mistake on my part. Now I actually want to retrieve that data from my database. I have no knowledge of databases but I would like to learn how it works. I would like a clean year 2021. So the question is how do I get the whole year 2020 from my database. Or more precisely, to learn; for example, how do I specify, 1 month to delete from that database. And how do I do that.

I think 'Bulk Database Editing' from the meteotemplate control panel is what you are looking for.
Your provider should give access to the database via phpmyadmin, where you can do everything you want ( use caution ).
A good starting point is a database backup ( just in case ; - )
