It happens bassically because APEX schema has not been granted with execute privileges for CTX_DDL and CTX_DOC. The note below it’s exactly about it:
The WWV_FLOW_HELP PACKAGE Status is Invalid After Installing Oracle Text (Doc ID 1335521.1)

The solution is simple:

mydb> grant execute on ctx_ddl to APEX_030200;
Grant succeeded.
mydb> grant execute on ctx_doc to APEX_030200;
Grant succeeded.
mydb> alter package APEX_030200.WWV_FLOW_HELP compile;
Package altered.
mydb> alter package APEX_030200.WWV_FLOW_HELP compile body;
Package body altered.

Have a nice day!
