[keycloak-user] Issues when modifying account.ftl

Hi, I added some attributes to registration page by following this link https://www.keycloak.org/docs/latest/server_development/index.html#modify... but I got this error: Caused by: freemarker.core.ParseException: Syntax error in template "account.ftl" in line 54, column 171: 11/28/2018 10:22:28 AMUsing ?html (legacy escaping) is not allowed when auto-escaping is on with a markup output format (HTML), to avoid double-escaping mistakes. 11/28/2018 10:22:28 AM at freemarker.core.FMParser.BuiltIn(FMParser.java:1188) .... Best, Sofiane.
