The errors on the homepage indicate that there are issues with the BP Profile View plugin and also BuddyPress Profile Tabs, I think the first thing I would do is remove these two plugins.
If you do not have access to Dashboard>>Plugins then you would need to FTP to your host and deleted their directories from the wp-content/plugins directory.
No idea if that would fix your issue with login in though but its the most obvious error.
Dude you’re a genuis.
Worked and I have access to wp-admin.
I guess I have to re-install those plugins?
You could try that but be prepared for it failing again, if it does then you need to raise a ticket on the support forums for those plugins
