In the browser I only see a blank page, like if the page was loading.
On the error log, there was no error message. In order to understand what was happening with the DB I turned on the debug mode in OJS and what I see now is some SQL queries (I guess is a log of the queries done by the OJS application):

The only āsuspiciousā thing is, at the beginning of the log file, the following WARNING:
PHP Warning: PHP Startup: Unable to load dynamic library 'pdo_pgsql' (tried: /usr/lib/php/20220829/pdo_pgsql (/usr/lib/php/20220829/pdo_pgsql: cannot open shared object file: No such file or directory), /usr/lib/php/20220829/pdo_pgsql.so (/usr/lib/php/20220829/pdo_pgsql.so: undefined symbol: pdo_parse_params)) in Unknown on line 0

Thank you for any advice.
