Badly formatted login error when username banned from creation
Closed, ResolvedPublic

webpage displaying login error

This might be multiple bugs that need to be split up.

I went to and clicked the 登录 link in the upper right hand corner (next to the user icon) to sign in. I presumed that my user account for User:Sharihareswara_(WMF) would get me in, thanks to SUL.

I know the login UI so it didn't bother me that it was labelled in a language I don't know. I filled in:

Username: Sharihareswara (WMF)
Password: [correct password]

and got the following error message in red (see screenshots):

<<table id="mw-protectedpagetext" class="plainlinks fmbox fmbox-warning" style="clear: both; margin: 0.2em 0; border: 1px solid #aaa; background: #f9f9f9; width: 100%; background: #FFDBDB; border: 1px solid #BB7070;"> <tr> <td class="mbox-text" style=""> <p>本用户已经被禁止创建,由于用户名“Sharihareswara (WMF)”和<a href="/wiki/MediaWiki:Titleblacklist" title="MediaWiki:Titleblacklist">本地</a>或<a href="//" class="extiw" title="m:Title blacklist">全域</a>黑名單<code> .*(apologise|war).* &lt;newaccountonly&gt;</code>配合。请确保用户名符合<a href="/wiki/Wikipedia:%E7%94%A8%E6%88%B7%E5%90%8D" title="Wikipedia:用户名">用户名方针</a>。如果需要协助,请参照<a href="/wiki/Wikipedia:%E8%B4%A6%E5%8F%B7%E8%AF%B7%E6%B1%82" title="Wikipedia:账号请求">Wikipedia:账号请求</a>所列指示直接向管理员申请账号或提交反馈。 </p> </td> </tr> </table> >

When I switched to English via the ":中文(简体)‎ | 中文(繁體)‎ | English | 日本語 | 한국어" choices just above that error and tried again, I got:

Login error
<The user name "Sharihareswara (WMF)" has been banned from creation. It matches the following blacklist entry: <code> .*(apologise|war).* &lt;newaccountonly&gt;</code>>

(My last name has the string "war" in it; never realized that before.)

However, if I tried logging in with an *incorrect* password, I got a well-formatted error "Login error: Incorrect password entered. Please try again." or "登录错误: 你输入的密码错误。请重试". That error message doesn't reveal any of the <table> or <code> tags to the user in the message.


  1. Zhwiki administrators or Chinese translators, could you fix the messaging for the "this username has been banned from creation"? I looked in and I couldn't figure out what message needs fixing, sorry.
  1. If the wiki's administrators have banned a particular user name from creation, but our SUL unification tries to make an account for them, then is it the right thing to do to still display a regular "wrong password" error message when someone tries to login with that username but gets the password wrong?

(1) is a due to bug 44718.
(2) is a real bug, but more or less related to bug 36939.

For that specific blacklist rule, I edited it to make it match word boundaries only[1], so Sumana you should be able to log in now.

This kind of error is also present on enwiki, it seems. Thought it might be related more to 44718. Not sure.

I've added S Page to the bug, the engineer who did the bulk of our team's work on account creation. He should be able to help hunt down what's going on here.
