[keycloak-user] Issues when modifying account.ftl

[So Be]

Hi,

I added some attributes to registration page by following this link
https://www.keycloak.org/docs/latest/server_development/index.html#modifying-extending-the-registration-form

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.

Best,

Sofiane.
