can you please try to reinstall the plugin and see if the problem persists?

I did that, already I can not figure out how this pliging works, is it auto delete or manual delete of notification how do you delete notification from menu bar?

You can delete them via phpmyadmin ow_notifications_notifications table

PM me your domain, admin details, and cpanel access details, I'll take a closer look at your problem. 

rather then me sending  my site info to you, could you please just tell me how you would normally how delete active notification that have been read? for example I am a user and I just login in I see in the upper right had corner of my site between the mailbox and users name there is a little box called notifications, I see in that box there are three new notifications so I go and read them, I am done with then now I don't need these notification anymore how to delete them? thats all I need to know thank you.    

The plugin malfunctions, I already told you, you can delete them via phpmyadmin ow_notifications_notifications table. However i need domain, admin details, and cpanel access details to find out the reason

mine do not auto delete as well 

Guys, please go to your phpmyadmin to the ow_notifications_notifications table and check the "VIEWED" column. What do you have there for these notifications which you still see in the website console?

ross i have hundreds of pages in that database in viewed column  is mainly 1   

as I said, unless you clear the ow_notifications_notifications table the list of notifications will be always there 

the problem with that is theres lots that are 0 so are unseen 

this table should be auto proned at say 10 notifications kept per user 

this is another thing adding to the database calls 

i am having huge speed issues as my site grows 
page load speed on first join my site is average 6.7 seconds which for oxwall script is dam good 
i am running 4gb memory cashe and max sql cashe 
i am adding mod pagespeed and APC cashing in the next week or so to my server and hope to get below 5 seconds 
 i have one account with 1000 friends and  lots of notification  page load times go up to 10.3 seconds 

and another account with 2000 friends and bucket loads of notifications page load time goes to 15 seconds 

so by the time a user get to 4000 friends the site will become useless to that user 
and the sql requests from all users will crash my server 

this is a huge issue and needs to be fixed 
until it is i can manual prone that databass and il have to work out how to limit users friends to a limit of 500 

notifications need to be auto proned
im chat needs some way of fixing sql request 
ether owall has a cashe system and cashe the users friends which in time will not work due to the size it would get to
or make the im not reload as a user goes from page to page as other site do ie facebook
and limit the amount of online users in the list to 30 or 40 with a view more online friends button  

load impact your site and see the sql requests go through the roof
