ORA-00980 synonym translation is no longer valid

Cause: The synonym used is based on a table, view, or synonym that no longer exists.

Action: Replace the synonym with the name of the object it references or re-create the synonym so that it refers to a valid table, view, or synonym.

I was created synonym and dblinks

Looks like somebody has renamed the table. Please check that.

Synonym will get invalid anytime a base object or the object it references is ALTERED.

So in addition to checking the Tables being altered, also check if your trigger is calling any other trigger or procedure and if that has been invalidated.
