Question JDatabaseMySQL Error in jos_fb_subscriptions [FIXED]

EDiT: A Fresh installation Fixed the bug!
Here is how i get this error.
1)I create a new topic and subscribe to it.
2)Then i delete the topic
3)Then i create another topic in the same category and if i have the subscribe checkbox i get an error:

500 - JDatabaseMySQL::query: 1062 - Duplicate entry '3-62' for key 'thread' SQL=INSERT INTO jos_fb_subscriptions (thread,userid) VALUES ('3','62')

Call stack
# Function Location
1 JSite->dispatch() index.php:68
2 JComponentHelper->renderComponent() includes\application.php:124
3 require_once() libraries\joomla\application\component\helper.php:162
4 include() components\com_kunena\kunena.php:578
5 JDatabaseMySQL->query() components\com_kunena\template\anditko_psp\post.php:572

7 JError->raise() libraries\joomla\error\error.php:171
8 JException->__construct() libraries\joomla\error\error.php:136

And here are some possible solutions:
1)In step 2 when a topic is deleted then we must remove the subscription entry as well.
2)Or use SQL UPDATE instead of SQL INSERT

Can someone fix this bug in the upcoming kunena version? :dry:

Hello,

I just tried to reproduce your issue on Kunena 1.5.9 and i can't.

I think that something is wrong in your kunena installation, it's impossible to have this mysql error because when you create an another topic the id is different, so i don't know where is your issue.

I installed a fresh version of kunena 1.5.9 and the bug was fixed. Thanx for leting me know that the problem was only on my site.

I edited my first post but you can delete it if you want.
