DUPLICATE: Error running Explain Plan: "ORA-00980: synonym translation is no longer valid." (4224299)

DUPLICATE OF SOL49941.

Running the Explain Plan on any query results in the following error:
ORA-00980: synonym translation is no longer valid.

TOAD_PLAN_TABLE is used for the Explain Plan command.

Toad Explain Plan table synonym is invalid because the Toad Explain Plan table was dropped at one point and its synonym still remains.

This error message is usually caused by a query trying to access invalid synonyms in your database that need to be dropped. Run the below query to find these synonyms:

select decode (s.owner,PUBLIC,PUBLIC SYNONYM ,
SYNONYM||s.owner||.)||s.synonym_name||;
from dba_synonyms s
where table_owner not in(SYSTEM,SYS)
and db_link is null
and not exists
(select 1
from dba_objects o
where s.table_owner=o.owner
and s.table_name=o.object_name);

RESOLUTION 1:
Re-install the Explain Plans Server Side Objects by using the Server Side Objects Wizard.

RESOLUTION 2:
Drop TOAD_PLAN_TABLE synonym and recreate the table and its synonym. Script provided below.

DROP PUBLIC SYNONYM TOAD_PLAN_TABLE;
