Hello there,
I have istalled useronline & wassup stats on my wordpress site…
And they works well.
then I installed wp-super-cache plugin witch capture page and save a copies of theme and store it…
so useronline and stats plugin don’t work good…
for example, wassup stats update visitor state on (wp-head) action…
is there any way to modify these plugins to work well, with out being affected by wp-super-chache…
I want to activate them together…
I am still waiting for your help…
Thanks…
