I made these changes. I did update the wp_options -tables (I have installed multisite) apq_options and apq_2_options
a. siteurl
b. home
and I´ve changed each posts in the apq_posts and apq_2_posts table
Then I changed settings in Softaculous
Now when I try to go into page (aurinkomajat.fi btw), it shows HTTP 500 error. Chrome says "database connection error" (or something equal in finnish language).
