[DND]

You opened 7 different topics about 7 different scripts. Who would want to help someone like this? Or better, someone that wants directly the fix without even knowing how it's made or how it affects the code?
And how someone above just said.. you need to have at least the minimum level of knowledge and my advice to stop using localhost if you cannot set it up properly.

It's not about what version you should use. It's good you are using the very updated version of everything, the question here is the code of the script you want to use (if you make up you mind first) and then update that script(all of them are old) to work with the updated version of your php/mariadb
