  • In ABP MVC, the “Back to my account” button is shown only if the current principal contains the impersonation claim (i.e., ICurrentUser.FindImpersonatorUserId() != null). So the fastest way to debug is to verify whether impersonation is still active (claims/cookies) and whether the toolbar item is still being contributed.

  1) Verify impersonation is actually active (claim exists)

  1. While impersonating, open your page and inspect the authenticated user’s claims (e.g., put a breakpoint / temporary log in any MVC action):
     • Check CurrentUser.FindImpersonatorUserId() is NOT null.
  2. If it’s null, the “back” button will not render. In that case, impersonation may still “look like it worked” (you’re logged in as the user) but the impersonator info wasn’t persisted (usually due to cookies/auth pipeline changes, custom account controller, reverse proxy cookie issues, etc.).

  2) Ensure the UI part (toolbar contribution) exists in your app

  For MVC, the button is not “magic”; it comes from the impersonation UI integration. If you customized your toolbar/layout/theme, you may have removed the contributor/view component that renders it.

  Make sure you followed the MVC impersonation UI setup:

  • Your Web module depends on the impersonation web module.
  • Your toolbar includes an item (often via a toolbar contributor) that conditionally adds the button when FindImpersonatorUserId() != null.
  • The endpoint POST ~/Account/BackToImpersonator exists (it’s the action the button posts to).

  If you’ve overridden AccountController, confirm it still inherits from the impersonation-enabled base controller as required by the docs.

  3) Quick isolation test: add the button manually

  To prove it’s only a UI/toolbar problem (not claims), temporarily add this to your main layout (or a toolbar area) and test while impersonating:

  @using Volo.Abp.Account.Localization
  @using Microsoft.AspNetCore.Mvc.Localization
  @inject IHtmlLocalizer<AccountResource> L
  
  <form method="post" data-ajaxForm="false" action="~/Account/BackToImpersonator">
      @Html.AntiForgeryToken()
      <button type="submit" class="btn btn-link text-danger">
          @L["BackToImpersonator"]
      </button>
  </form>
  

  • If this appears and works, your problem is toolbar contributor / theme component not being executed or not rendering.
  • If it posts but fails, then it’s not a rendering problem; check the action route and auth cookies/claims.

  4) Common real cause: theme/mobile toolbar placement

  There is a known case where the button is not visible depending on responsive/mobile toolbar placement (especially with LeptonX). In older versions it was fixed by upgrading (example reported/fixed in later versions for mobile view). Even on desktop, if your theme moved the user menu into a different place, the button may now be under the username menu instead of the top bar.

  5) Confirm you didn’t restrict the toolbar contributor to a different toolbar

  If you have custom IToolbarContributor code, ensure it’s contributing to the toolbar your layout uses (e.g., StandardToolbars.Main). A wrong toolbar name check can prevent the item from being added.

  hi

  Account pro module will try to find AbpClaimTypes.ImpersonatorUserId in the current user. Then display the backto component.

  if(currentUser.FindImpersonatorUserId() != null)
  {
      context.Menu.AddItem(
          new ApplicationMenuItem(
              "Account.BackToImpersonator",
              accountResource["BackToImpersonator"],
              url: "~/Account/BackToImpersonator",
              icon: "fa fa-undo",
              order: int.MaxValue - 1000).UseComponent<ImpersonationWithTextViewComponent>());
  }
  

  Can you display all claims on your index page?

  How can I reproduce it in a new template? Or can you share a demo project?

  Thanks.
