[Erp5-dev] "requested resource does not exist" Error

[Rafael Monnerat]

Hi,

Some months ago one student that I was starting to help had some similar 
problems because he installed by mistake 2 ERP5 sites using the same 
MYSQL database (test test) and this is totally wrong.

One reference related to it:
