Hi
Seems that you have the numisdata
TLD active in Ontology main
but you have not loaded the ontology.
Check if you have the numisdata
TLD in Ontology -> Ontology main

find in the TLD
component numisdata
and check if the ontology is active, if is active change it to «No»

Log out and log back in to check if the error has disappeared.
In >v6.4 the main ontology controls what is active and used. If you have the TLD active but the ontology is not loaded you will get errors as you said.
And if your installation has not the numisdata
ontology in Ontologies main
say me to find any other cause.
Best
