Thank you very much.
Everything is coming back.

I have to find now how to add friends

The OssnDataBaseException is caused by a bug in the Latest Members component.

Edit line #15 of the file components/LatestMembers/widgets/friends_widget.php
to look like

//  'order_by' => 'r.relation_id DESC'

How can i do to remove the component without reinstalling OSSN. I dont have anymore access to the admin page

I don't know what to do, i want to remove the component
after the change, below what i get

OssnDatabaseException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'r.relation_id' in 'order clause'

Adding the iframe worked with a Google calendar as well. Thanks for the suggestion.

If it helps anyone.
Having messed with this for a while.
I have found that a third party calendar works awesome in this component.
I use a calendar from teamup.com.
Simple to integrate, just place it in a iframe in the 'calendar/plugins/default/calendar/calendar.php'

ie,, replace all with this
<p>
<iframe id="yourcalendarhere" title="Calendar" width="100%" height="600" src="https://teamup.com/your code here"></iframe>
</p>

Useful component. Too bad it was thought only in English. I could make the changes to write it in multiple languages ​​I'll think about it.

thats simple but so good. Thanks for this component.
