i want to find error or bugs from site by using link from another site. how can i come to know about error is occurring? if there error accures then i should get massege that there is an error in that site.
As in you want all errors to be reported somewhere else? do you mean PHP errors, or errors such as 404 etc?
for example in my blog i look in W3 CSS i find my blog there are so many errors and i can't find it and maybe can you give some tips how to repair some errors in my blog thanks
