Your last suggestion is the most easy one! Thanks.
On my website (Joomla 3) I have next to jsvisit Visitor Counter the VCNT visitor counter installed. I notice that the score of jsvisit is is much higher than VCNT (currently 65 vs. 27). My experience is that VCNT is reliable, Do you have any idea what causes this difference and how to solve this? In the plugin the 3 Geolocation Servers are set to No.
Correct visitor counting requires that cookies are allowed on your website for the use of the time interval of 120 minutes. If this is not the case, the visitor counter becomes a hit counter because every page view is counted.
You may verify this by just reloading your called webpage. If counter is not incremented counting works correctly.
