Whoops something went wrong....please help

I'm installing akaunting to my localhost server but on the third step of installation, the settings, i face a problem. Setting the language ok, setting up the tables ok, but the third step where you fill up the company profile it returns me the following error:

SQLSTATE[HY000] [1045] Access denied for user 'forge'@'localhost' (using password: NO) (SQL: insert into `ak_companies` (`domain`, `updated_at`, `created_at`) values

Don't know what I did wrong...but I just spent my last 5 hours trying to figure this out.

Need help please... :(

Thank you.

What are you using for localhost? I would suggest XAMPP.

It LAMP running raspbian rasp 3

Please anybody help? has anyone experienced this error before? Still can't use my akaunting till this day...
