Forum very bad problem with vb4 ...
 

after I upgrade i've a very big issue that sometimes thread page url doesn't update . for example it shows page 2 when I click and go to page 3 !!! .

I have to rebuild post caches every time this problem occur to solve it and I'm running a big with over 100K users and there are many threads . it's not the logical way .

is there anything wrong ?

and is there any way to solve it more quickly than rebuild caches ?

thanks
