The web is not working

It has happened to me 4 times: I start to configure the page and from one moment to another what is broken.
I have reinstalled wordpress even create a new database and the same thing happens.
I don’t know if is a problem with plugins??
Before to leave the theme I need to know if it can be fixed…It is giving me a lot of work because I had to confirm everything every time …
I would like to send you a shot screen…
thanks

Hello,

Yes, it can be a plugin issue. Just activate plugins one-by-one and check if everything works as it should.

Kind Regards, Roman.
