I have just upgraded to Jforum 2.1.9 , I can login but although it says 'Our users have posted a total of 11,205' messages , no messages, topics or forums are listed. I'm using Tomcat 7.0.30 and MySql 5.0.77, I did the upgrade as follows:

Ran mysqldump on my database
Created a new database and populated with output of mysqldump
Modified my existing 2.1.6 installation to use new database and checked that it still worked
Unzipped jforum-2.1.9.zip to local directory
Changed 2.1.6 installation to loook back at its original database
Ran mysql_2.1.6_to_2.1.7.sql against the new database
Ran mysql_2.1.7_to_2.1.8.sql against the new database
(Couldnt see an upgrade script for 2.1.8 to 2.1.9)
Created META-INF/context.xml (which defines a data source for new database, not sur eif required)
Copied WEB-INF/config/jforum-custom.conf from my 2.1.6 installation into WEB-INF/config in jforum2.1.9 directory in same place and modifed to point to new database
Modified forum.link and homepage link to point to new deploy path
Deployed this modified version

So I now have deployed:

http://machinename/forum (2.1.6 pointing to old database)
http://machinename/forum2.1.9 (2.1.9 pointing to new database)

As I said earlier I can get to http://machinename/forum2.1.9 and login but no topics/messages ectera are listed. Similarly if I go into Admin Control Panel Users and Groups looks okay but Forums is empty

If I go to the database itself and look at jforum_topics and jforum_forums the data is there.

I then noticed the lucene section in Admin and that the Number of documents was zero. So I configured a date range and created a new index, the Number of Documents field increased. If I then go back to the forum and do a search the search says it has found some documents but still does not show any of the results.
You showed up just in time for the waffles! And this tiny ad:
