What does the error log of your hosting account say? Do you have wp_debug set to true in the wp-config file? If so, what is the output in the debug.log (can be found in wp-content/debug.log)

Hi dear
I have no problems hosting an account.

Do you have wp_debug set to true in the wp-config file?

I have not this file

So how to solve these problems?

Now it is working because I installed the theme
Minimalist means problem with the theme I created it so what is a mistake I did
