Hi Drashida
It seems that at least some of your events have not been assigned a date, so they will not display.
Also, past events do not show on the map (but that is not the problem).
In addition to that, none of your events has a location assigned to them.
This seems to be the same for your places.
On further investigation, I can see that you have no locations left in your multilocation settings.
It looks like there has been some severe data loss, so I hope you have a database backup, or contact your host to see whether they might be able to restore an earlier version.
All your GD plugins also need updating AFTER you restore the data.
PS: Please post your admin details in a private message if you want any of the other admins to help too; they can’t see the site because it is in Coming Soon mode.
