Check the Flarum log and webserver log for any error message https://docs.flarum.org/troubleshoot

If there's nothing in the Flarum log, it might be a general PHP error or warning that will be logged to the webserver or general system log file of the server.

finally, I find the bug:

window.close(); window.opener.app.authenticationComplete({"email":"omTsc6gIRTSQnsomr6qZoiUeug4k@wx","token":"uzuk75qdzXX1PSXidaKHdhzzCQlGcw2Si9MfQpAD","provided":["email"]});

while Uncaught TypeError: Cannot read property 'app' of null
which means no (opener)!
"window.opener" is null / undefined. for the empty page load nothing, just the <script>

Finally I got it:
Here is my auth flow:
/auth/passport => auth.laravel.com => wechat.auth.server.com

for the login with button(wechat login) opened a new window(logInPopup with status=no,scrollbars=yes,resizable=no etc).
while I use the login button in a wechat App, then there is only one window(for wechat app restrict, so window.opener is null ), it can't popup a windows to redirect to wechat auth service then go back to the main window.
SO, I need a solution without popup a auth window, instead, I need go /auth/passport directly then go back to home page.
how to solve this? Thanks.
