This is a small but VERY powerful statistics system that I found that is free. It would be an AWSOME addition as a module!!!
Here is how I installed it...
1. Copy the "MecStats" directory up to the root of your CMS installation.
2. Edit the "admin/lang/en_US/admin.inc.php" file as follows...
at the end of the file, just before the "?>" add
Close and save the file.$lang['admin']['adminstats'] = 'View Site Statistics'; //needs translation
3. Edit the "admin/menu.php" file as follows...
around line 69, find the following text...
add directly below it, before the "[/quote]
Close and save the file.
4. Edit the main "index.php" file as follows...
Just above the "echo $html;" line add
Close and save the file.require('mecstats/hit.inc');
And that is it!!! You are now logging all of the hits to your site, Browsers, search engines, robots, etc.!!!!!!!
It has been working great for me!!! Let me know what you all think!!!
Remember, a module would be great!!!
