Broke my wiki by installing Standard Flavor via Extension Manager

Hello,

I was exploring xwiki and its features. So I’ve decided to install Standard Flavor on a running wiki and now I can’t do anything. There’s an image down below that shows the problems I’ve currently run into.

  1. When I’m trying to login (I’ve set up LDAP authentication and left a couple local accounts to administrate my wiki), nothing happens, I’m left on the login page and no failure message is shown to me.
  2. Somehow icons (supposedly) are not shown, instead, I get some text like $services.icon.renderHTML(‘user’)

UPD. Logged in as superadmin. That’s quite a mess of a wiki :expressionless:

Please, help me fix this mess
