HURRA !! 😊
After adding the nssha1.so and nscache.so modules, which the welcome page complained about and adding the Pl/PgSql language to my database, I could finally click the 'Next ->' button creating the database.
I got all the way through to "current" error:
select email from cc_users where rownum = 1
I will shortly put my very crude 'problem list' into the file-storage hoping it can be of any use. I cannot promise to maintain, because I am awfull at forgetting my own mistakes 😉.
Thanks all,
