Reply To: Activity stream disappears in WordPress dashboard
Hi @skvirly,
unfortunately, i think nothing about your issue, except that it seems that something is interfering somewhere.
The best practice in such case is to start from the begin.
Activate WordPress and 2015 theme. Check that anything is correctly working.
Then activate BuddyPress. Re-check.
Then bbPress. Re-check.
Then, activate Sweet Date theme. Re-check.
If all is Ok, and only if all, you now have a base install of WP/BP/bbP and your theme working correctly. There shouldn’t be any notice or warning at this stage. If you got one, it’s a probleme with the theme.
If this is ok, you add one plugin. And re-check. This normally make things easier to debug.
As it is apparently related to xprofile, it could be possible that if you use contactform plugin for your register page, that something is wrong with that plugin. But this is only a hypothesis, not a certainty.
Note that php memory_limit of 128 mo is enought to run a script, when BP is running on a single install. Aside, note also it’s default for php 5.6 version.
Happy debuging.
