Unable to add products, nor categories images

[vodgardens]

Hello,

 

I don't understand, each time I try to add a new product, or a new categorie image, it does not work.

 

I don't get any error message, simply a king of page not found message. It is not a 404 error, but it seems like the page is not on my server (but I know it is).

 

I click on the Add button, then I just type the product name (first, I typed the price, I added the image, etc., but as it was not working, I decided to only add the product name), and then I click on "Preview" (the only button available).

 

Sometimes I get a previsualisation, sometimes I don't. When I get the previzualisation, I then click on the "Insert" button, and... nothing happens.

 

The title of the page becomes "Server not found", and it is written: "Impossible to display the page".

 

But as I told you, I get no error message from oscommerce.

 

I don't know what is happening, and I don't know what to do.

 

Any ideas?

 

Thanks for your help
