@akkoxe check inside the browser console, if you are getting errors. It will help to debug the issue.
Hi @akkoxe,
I think your theme is using a custom buddypress/activity/post-form.php
template as there are two textarea tags. Can you confirm ?
The error you get about the undefined message is there because the Nouveau JS Templates are not being included.
BTW You can fix it by switching back to the Legacy template pack from your BuddyPress Options Administration screen.
Hello. Sorry for the late answer, I checked everything. Before BP 3.0 I used Nouveau as a additional plugin. After the 3.0 update, I deleted it and start use Nouveau in new BP. Now I can not change to default, because I need exactly Novau for my website.
I do not use any custom forms and pages (I change all files for default). My template is Newspaper. I created a new test wordpres installation for check the issues, and there everything is loaded in the same configuration on new website. I think it is a some issues with files and try to change all files to default (theme, wp, BP), but it is not help.
So most likely the problem is in the database, may be with a settings (may be it was then I update plugin on 3.0 with additional active Nouveau plugin, but it is not exactly).
How to reset all settings to default in DB?
UPD
I installed some plugins on new test wordpress, and activity stop working again.
If user do not login – activity stream is ok, but if user logged in – stream can’t loading. Why?
