HTTP ERROR 500 install

yes i understood this but i don't know how to do it... help me please...

I see in your printscreen you have a tab Cpanel-Tools open.
search for phpMyAdmin there (or Adminer) and consult the information the host offers.

yes, I understood that it should be done from the database... the problem is different, I don't know how to make the respective records in the database...
I don't know how to enter these...
Then, in the config_table create a new record:
config_name = config_url
config_value = //ajax.googleapis.com/ajax/libs/jquery/3.7.1/jquery.min.js
is dynamic = 0

Search and you shall find.

There's a ton of information in the Support (even disregarding the whole internet)

e.g.
https://www.phpbb.com/support/docs/en/3 ... hpmyadmin/

I tried to enter config_table create a new record:
config_name = config_url
config_value = //ajax.googleapis.com/ajax/libs/jquery/3.7.1/jquery.min.js

You have to create a new record
So open phpbb_config and click "create new record"

I tried to enter config_table create a new record:

If you want to create the field using SQL, then you have to write an SQL query. e.g.

INSERT INTO `phpbb_config` (`config_name`, `config_value`, `is_dynamic`) VALUES ('', '', '0')
Edit the SQL to include the values (which I already mentioned)

or

Just add the record using the graphical interface (as janus_zonstraal proposed)
