there's nothing in the error log of the server about the problem. but you can reproduce the problem by trying this.
url is www.dagospo.com/MCBinvoice
login- 'raport' , 'password' - 12345 click edit to edit the invoice of the client, then click the tab items and under the tab click the add invoice items. choose any item from the option and place any value under quantity then click save item. the web page with this problem pops up The connection was reset. the connection to the server was reset while the page was loading.
if i try to enter the url - www.dagospo.com/MCBinvoice
the same problem will occur. i have to clear the cache again and re-enter the url. this time it will work. but if you click same sequence of pages as the above the problem will be the same and you can't enter the url - www.dagospo.com/MCBinvoice
until you clear the cache again
thanks for your help
