Yes, that's what i did. And no effect. But i'm gonna test your advices in another Joomla-Installation now. Gonna report my results in a few secs...
EDIT: Okay, i did not test it - although i was about to do it, but then i just fof fun searched for the expression "%kide%" in the whole database and found it also in 'com_menu'. I'm not yet very firm dealing with joomla tables in database, but okay, that gotta be the menu item i created in order to call the shoutbox. When i upgraded the shoutbox i just uninstalled the component and did NOT delete this menu item. So it looks to me that this is the cause for the display limit of the shouts in the shoutbox. Here are the entries of the row "params" in table jos_menu:
solo_registrados=
msgs_limit=36
msgs_saved=60
max_word=20
max_letters=2000
sesion_time=10
refresh_time=5
refresh_time_sesion=60
perfil_link=
page_title=
show_page_title=1
pageclass_sfx=
menu_image=-1
secure=0
So it looks to me as it did NOT adjust my new settings.
Okay, looks like I got it wrong - now i found that i can adjust the settings as well in "administrator -> components -> kide shoutbox" and again in the advanced settings of the menu entry. Gotta admit, that i did not have a look at these settings there. I assume the settings in the components menu work as a template for new menu items, but these do not adjust to changes in the component...
Thx for your help and time!
