This was reported some days ago, and appears that for some reason the smlies cache gets null. First of all, do you have any smilies? (Admin Panel -> Smlies). If so, try reseting the cache at Admin Panel -> Cache -> Smiles -> Reload

If the smilies don't come with the source files of Jforum then I do not have them. I had built Jforum from the source.

When go to cache link in the Admin Control Panel >>> this is what I get

The smilies are in the dump file - for example, WEB-INF/config/database/mysql/mysql_data_dump.sql (the same for other databases)

Hi Rafael,

Please click on http://javalive.com and click on a topic you will understand what I am trying to say.
Want to mention here that this used to work the first time I set it up. Please help its very critical as it is a live forum.

Right, I understand, but there are smilies in the database or not? Take a look at the table jforum_smilies.

As a "fix" for that, open the file PostCommon.java, and in the line 267 you'll find the code which is causing problem. Before that line, there is a call to



which, for some reason, is null. A workaround would be to check for null before going to the for() loop:



That will prevent the exception. Now, we should discover why it is happening. If you have the smiles in the database, and if you reset the cache at Admin Panel -> Cache -> Smiles -> Reload, then a deeper debug is necessary.

For now, can you tell if the application is running on a single server or clustered environment?

Right now it is running on a single VPS server.

Right then. So, it's hard to tell exactly why this is happening, as it always worked, and, as you said, it started out of the blue. Something (don't know what yet) is invalidating the smilies cache.

I will try out your solution and see what happens. By the way I would like to tell you that I had migrated the data from a xoops newbb forum to Jforum.

Thanks
