Reverse all file and template edits and run these queries:
[sql]DELETE FROM phrasetype WHERE phrasetypeid='716';
DELETE FROM phrase WHERE varname LIKE '%shoutbox%';
DELETE FROM setting WHERE varname LIKE 'shoutbox%';
DELETE FROM settinggroup WHERE grouptitle='shoutbox';
ALTER TABLE language DROP phrasegroup_shoutbox;
ALTER TABLE usergroup DROP shoutboxpermissions, DROP shouthierarchy;
ALTER TABLE user DROP shouts, DROP shoutbanned;
DROP TABLE shoutbox_posts;[/sql]

Ok i have redone everything i can think of and a square has appeared
can you take a look at www.ukctest.geezzaa.com.
Very anxious to get this working on my main site

All I see is a standard vB3 RC2. Did you edit/add the templates?

my template was named shoutbox_iframe_shoubits
i had an S at the end... thanks for the help

Yes i have re checked twice

Well, if you have ran the installer, done all the file edits, and added/edited the templates, then it should work perfectly.

Just a bit offtopic.

Link14716 are you really 15 ?

Yep. :)

I updated from RC1 to Final and all of the phrases aren't working.

Try editing a phrase and saving it. If not, can you check if the phrases exist? (In the phrase manager, most of the phrase are located in the "Shoutbox Hack" phrasegroup).
