i get this when i open the Photo Gallery page in sharepoint.
The "PictureLibraryLister" Web Part appears to be causing a problem.
Web Parts Maintenance Page: If you have permission, you can use this
page to temporarily disable Web Parts or remove personal settings. For
more information, contact your site administrator.
When i edit the web.config to make the page display the exact error, i
get:
Description: An unhandled exception occurred during the execution of
the current web request. Please review the stack trace for more
information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not
set to an instance of an object.
Source Error:
The source code that generated this unhandled exception can only be
shown when compiled in debug mode. To enable this, please follow one of
the below steps, then request the URL:
1. Add a "Debug=true" directive at the top of the file that generated
the error. Example:
<%@ Page Language="C#" Debug="true" %>
or:
2) Add the following section to the configuration file of your
application:
<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>
Note that this second technique will cause all files within a given
application to be compiled in debug mode. The first technique will
cause only that particular file to be compiled in debug mode.
Important: Running applications in debug mode does incur a
memory/performance overhead. You should make sure that an application
has debugging disabled before deploying into production scenario.
Stack Trace:
[NullReferenceException: Object reference not set to an instance of an
object.]
