I would suspect you have removed the messabox usercontrol from the forum master page, as when the OnLoginError fires all it does is look for the messagebox and display the error.
Make sure you have the following in your master / forum master template
Hi, I am having the same problem, however the only change I've made is that I've added nForum to an existing website that has it's own user database (edited web.config provider). If I use the nForum login page, I get an error (see below). If I use my own login page my website works fine, but won't browse to forum category pages (although the forum home page shows that I am logged in ok.)

Actually, on re-reading the original post, the problem is not the same. My problem happens on log in with the correct credentials (not the wrong ones).
I know this is an old topic,but I had exactly the same issue just today (integrating nForum into an existing site) so just in case someone has the same problem.
The problem was my own registration process assigned my own member type, but did not have the properties that are attached to the 'Forum User' member type (such as "Is admin", "Is banned" etc).
It was just a case of adding those properties to my own existing member type and problem was sorted.
Error when login is failed nForum
Dear Lee, your forum is awesome...! However
i am trying to integrate your forum into existing starter kit..by arrenging your forum inside protected site like picture below
The register and login is located outside your forum to make sure only authorized acces can see the content
The problem is happen when we insert wrong value in register and login (e.g. wrong login password). The error come up like this
Any advise, really appreciated..
Can you copy and paste the entire error in here please, the screen shot has trimmed off some of the error message

Make sure you have the following in your master / forum master template
At the top under the @Master directive
In the Contentplaceholder at the top
<div class="error" id="error" style="display:none;"><a onClick="document.getElementById('error').style.display = 'none'" href="#"><img alt="Remove message" src="/nforum/img/msg/close.png" /></a></div> <msg:MessageBox ID="msgBox" ShowCloseButton="true" runat="server" Visible="false" />If you have these, then have you changed the logincontrol name? Or anything else to do with the membership?
You are right .. a realigned the content structure and it's become normal :)

I am using Umbraco 4.7.0 and nForum 1.2.

HTH.
So if we have any other Member types they all have to have the nForum member properties?
All of them or just some?
Sounds like a bug to me - Lee?
is working on a reply...
