We have had various people working on our Magento e-commerce website. Someone changed the code so that all errors are visible to the consumer.
We have tried a number of changes to the code to correct this, but without success.
You must inform us what measures you will take and you must supply us with folder names, file names and the exact code changed in order to be paid.
This should be a very easy and quick fix, especially if you are true Magento expert. Budget $30 - $50.
