After i rebuild cache it jump to a page where it says, "ERROR The requested page could not be found".
No Server Error log and all file are fine with health check.
I disable all the plugins.
Then in admin debug mode the error comes a little clearer
Jump to error page but also displays.
"Route admin.php/ could not be found."
So i search this error but cant find much about this.
Anyone had the same problem.
im still at xenforo 1.3.3 and i dont wanna update if this error breaks something.
