Getting HTTP 404 - File Not Found when creating Items

Question

This happens when I try to create an item of any type. I can edit items already created, but I cannot create any new items.
Take the Text Control for example:
When I click on the Text item icon, I get the page that prompts for the Text Control Type. I select one, then I wait and get the HTTP 404. This happens with all items. For items that do not have subtypes, I get the error immediately.
Any suggestions?

I have some major work to do. This might require a call to Oracle.
Udump trace file reveals the following for each attemp to create an item:
ksedmp: internal or fatal error
ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] [_opidsa+360] [PC:0x2080540] [ADDR:0x0] [UNABLE_TO_READ] []
Current SQL statement for this session:
select
nvl(htf.escape_sc(p.plug_name),wwv_flow_lang.system_message('CREATE_ITEM_WIZ.NO_REGION')) plug_name,
i.item_sequence,
i.name,
i.prompt,
nvl(i.item_plug_id,0) item_plug_id,
i.DISPLAY_AS
from
wwv_flow_step_items i, wwv_flow_page_plugs p
where
i.flow_step_id = :FB_FLOW_PAGE_ID and i.flow_id = :FB_FLOW_ID
and
p.id (+) = i.item_plug_id
order by nvl(item_plug_id,0), item_sequence
I shut down the database. I get this when attempting to restart:
SQL>
Connected.
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup
