Hmmm, strange. You don't get any error message? What URL does your 
browser show in the location bar when you get that empty page?

No. The empty constructor just does nothing, that's fine in that case.
MyResearch/Account.php hasn't changed since SVN r1816. That was before 
RC2. And for me account creation works in RC2 and later with DB 
authentication. So there may be some issue with your specific setup...

Have you tried some kind of debug output in processInput()? If it really 
isn't called one of the following conditions must be true:
- clicking "submit" on the account creation page doesn't take you to 
MyResearch/Account again
- in config.ini in the [Authentication] method is not set to DB (or for 
whatever reason your VuFind installation doesn't know at line 41 in 
Account.php it is set to DB)
- clicking "submit" on the account creation page doesn't POST a "submit" 
parameter back to MyResearch/Account
These are the conditions checked before processInput() is executed in 
Account.php. So check by adding some brute force debugging output to 
Account.php if these conditions are met, eg. by adding
print_r($_POST);
print_r($configArray);
at the beginning (but behind global $configArray) of function launch() 
in Account.php...

I have no idea... Try debugging that thing in your setup and tell us the 
results. They may give helpful clues where the specific problem is in 
your setup and if we need to change something in Account.php to better 
avoid such problems...
Hmm: What user interface theme are you using?

Have you changed the authentication method in the config.ini form LDAP (this is the default authentication method) to DB?

Have a nice day!

Correct. No error message. The page just comes back with a blank form. For example, try:

  http://vufind.library.nd.edu/index.php?module=MyResearch&action=Account

Okay. My specific set-up. I will look around some more.

This is helpful. 'More later.

The out-of-the-box default interface. I have done no user interface customization, yet.

OK, there is something wrong with your RewriteRule setup in the Apache 
configuration. You shouldn't end up with this URL in the browser address 
bar.
That's what happens here: The data in the "create an account" form is 
HTTP POSTed to /MyResearch/Account, the web server replies with a HTTP 
301 redirect to /index.php?module=MyResearch&action=Account before any 
of the entered and POSTed data reaches VuFind because of a RewriteRule. 
The browser then follows this redirection and accesses 
/index.php?module=MyResearch&action=Account but doesn't POST the data 
again to that address (POST doesn't work with redirections). So the 
account data never gets through to Account.php. That's why you end up 
with an empty form and no account. VuFind doesn't know somebody just 
tried to create an account...

Have you put a R flag into the VuFind RewriteRules, like
RewriteRule   ^([^/]+)/(.+)$ index.php?module=$1&action=$2 [B,L,RQSA]
or something?
There is no need to do that and that always fails when data is POSTed to 
VuFind (though VuFind usually uses GET to send data to the server and 
GET works fine with redirects).

Thanks to Till, I have resolved this issue. Specifically, the following was in my Rewrite rules:

      RewriteBase /vufind

But alas, my VUFind installation is at the root of my Web server. So, after changing the rules to the following, I am able to create accounts:

      RewriteBase /

Now I can also tag, comment, add favorites, etc.
