Click to expand...

What do you mean by that?
If the software hangs, it looks like to be a multithreading problem. Are you trying to change the UI or perform some UI task in a PHP script?

i have normal php script
for example :
there are 2 links ()
leads to two different pages

now i opened first link - now its fully loaded (it also has datatables jquery)
now i click on second link - Some times 1 in 10 times what happens is first page doesn’t goes of and 2 page also loads

so here i see 2 pages like content of two pages in one
(Gives error - can not load already loaded datatables)

(Not using any ajax)
