I have a working site [login to view URL] which is the most up to date code base that i have. It has the following problems: 1: In the admin panel when i click on modules the page is blank with only the options to "save configuration" which when pressed breaks the site. 2: There is a front end ability to "submit" a url and then go through the process of adding a product. When i submit a url it goes to a blank white page. This needs fixing 3: There is a backend ability to add a product/article. When i add the article sometimes the product image, or thumb on front page does not show. Not all the time, i was unable to recreate what causes this to happen. Sometimes it happens, sometimes it does not. I am unsure what the problem with the code is to make this happen. 4: Once you have done that i need you to install a clean version of the code onto another domain, without any users or products/articles so that i can test to see how it works as a new install 5: Once 4 is done i need you to install it again to another domain and import a list of users and passwords i have from another version of this script and check to see if all is working I need someone who is good with drupal, i do not want anyone who has no experience with drupal as i have tried this before and it wastes all of my time and effort. If you have experience with drupal then please provide examples. I will choose someone as soon as i see they are experienced. If you are ok to start straight away then please bid, i will upload some cash to escrow so we can get started. If you do a good job then i will give you some more work as well.
