I also had to change the longblob settings in my MySQL server to get this to work on my installation, if I remember correctly. I kept getting "packet too large" errors. I think I discovered the answer to the problem through looking at my log files.

The following article has some information on the problem, if it happens to crop up.

David,

Chris Rishel (the lead programmer) can comment more on this next
week, he is out now, so I will attempt to address it as best I
can.

You are possibly running into a PHP configuration issue here, but
the error message makes me wonder if there is an additional
problem.

PHP has a max_upload_filesize variable which is set in the
php.ini file.  For our implementation, it is set to 2MB, which is
the default.  But some server admininstrators decrease it.

If you don't have access to the php.ini file, or can't convince
the server administrator to up the value, you may be able to
solve this problem yourself by putting a file named .htaccess in
the archon folder, with the following text included:

php_value upload_max_filesize 3M

Or whatever MB you want it increased to.  However, using
.htaccess will only work if you are using apache as the
webserver.

Thanks,

Chris
