am having a little trouble if anyone can help please.?
after doing the "order by 1--" through to "--10" the website just reloads but "--11" gives me this message:
"Query Error : There is an error in Query, Database Connection Was Successful though."
am i right in thinking there's 10 column here.? if so why don't i get a error message some where between 1-10, as my vulnerable column.? sorry for seeming so thick as the comments state this is a good tut so am in no doubt it is, am just a noob at the min trying to learn
