Hi Antonio,
I am sorry for the late reply.
Can you edit the file which I gave you in line: 29 and replace the existing code with this instead:
$disableApps = array('apps','badges','calendar','feeds','followers','friends','groups','k2','kunena','links','photos','profiles','shares','story','tasks','blog','broadcast','events','discuss','komento');
These are the list of apps available to be filtered. You can remove the one that you want to be displayed. If this doesn't fix the issue, perhaps you can provide us with the backend access and FTP access so that we can fix this issue on your site much quicker.
By the way, I am really sorry but currently we quite tied up with our own internal development and we wouldn't be able to assist you further after this issue is fixed.
If this is a priority, please do post them on our sales section at
https://crm.stackideas.com and our sales department would get back to you with a proper quote.
Please advise.
Thanks.
