I deactivated all plugins but BP and it did not help…
Then I reactivated BP and it looks like it is working. Go figure…

Thanks for you help @mercime

I also see the following in the error log:

As for the plugins:
* BP Multilingual
* WPML plugins
* Events manager

This is new installation, I did not do any changes to any of the files from the error log.
