So here is my problem. My father had problems on his computer so I lend him mine. He installed on my laptop a software called TX3 Configurator. By installing this software it also installed SQL Server.
Since my father didn't needed my computer anymore, I removed the software (TX3 Configurator) but it didn't removed SQL Server with it. I went in Apps and features and uninstall it "manually".
Today i tried to do stuff for school and went on this website https://simulator.electude.com/ and this message appeared in the top left corner :
Warning: pg_connect(): Unable to connect to PostgreSQL server: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"? in /home/dba_man/simulator/site/db.php on line 18
Warning: pg_query_params() expects parameter 1 to be resource, boolean given in /home/dba_man/simulator/site/db.php on line 50
Can someone help me ? I only use my laptop for basic stuff like school and games. Right now everything else seems to work, I only can't connect to the electude simulator ( a website i need to go on for school/learn )
