There is something wrong with wp-slimstat.js. Unfortunately, I’m a bit stumped what `SlimStatParams var SlimStat =...` is supposed to be. * Plugin Contributor [Jason Crouse](https://wordpress.org/support/users/coolmann/) * (@coolmann) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-slimstatparams-is-not-defined/#post-3382697) * Hi there, * let’s work together on trying to catch this bug. I have a new beta ready for testing, would you help me test it and see how it goes? * Contact me with your name and a reference to this post: * [http://www.duechiacchiere.it/contatto](http://www.duechiacchiere.it/contatto) * Thanks, Camu * Plugin Contributor [Jason Crouse](https://wordpress.org/support/users/coolmann/) * (@coolmann) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-slimstatparams-is-not-defined/#post-3382802) * [@all](https://wordpress.org/support/users/all/), * a new version has just been released, which fixes the problem according to my tests. Please feel free to upgrade and report back to confirm that the issue is now resolved. * Thank you, Camu * PS: a vote for my plugin would be a nice way to show your appreciation! * Thread Starter [JohnRDOrazio](https://wordpress.org/support/users/lwangaman/) * (@lwangaman) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-slimstatparams-is-not-defined/#post-3382803) * Yes that fixes for me!

It does not work at all, even with JS disabled I get no tracking. * With FireBug’s console window, I was able to determine that wp-slimstat.js.php returns `-110 : invalid public key`. * Since 2.9, wp-slimstat also completely breaks javascript if W3TC’s “minify” feature is enabled. * [pepe](https://wordpress.org/support/users/pputzer/) * (@pputzer) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-slimstatparams-is-not-defined/#post-3382810) * When JS mode is enabled, wp-slimstat-js.php returns `-203 : Visit not tracked` * Plugin Contributor [Jason Crouse](https://wordpress.org/support/users/coolmann/) * (@coolmann) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-slimstatparams-is-not-defined/#post-3382811) * Hi Pepe, * -203 means that the WP SlimStat thinks that the IP address of your visitors is not correct, for some reason. * What’s the URL of your site, again? * Thanks, Camu * [pepe](https://wordpress.org/support/users/pputzer/) * (@pputzer) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-slimstatparams-is-not-defined/#post-3382812) * That’s the local dev install, so I guess it gets 127.0.0.1 – the -203 would be sort of OK then for this case. But what’s going on when JS mode is disabled? * [pepe](https://wordpress.org/support/users/pputzer/) * (@pputzer) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-slimstatparams-is-not-defined/#post-3382813) * What’s the WP handle of your JS file? I think I’ve got an idea why things completely break on the production site. I’ve got minification enabled (W3TC minify for HTML and inline JS and Script Optimizer for general JS and CSS). I guess the minification routine doesn’t like the embedded VBScript. * Plugin Contributor [Jason Crouse](https://wordpress.org/support/users/coolmann/) * (@coolmann) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-slimstatparams-is-not-defined/#post-3382814) * I think W3TC is adding the javascript params AFTER the script that needs them. Other users have reported the same problem: * [http://wordpress.stackexchange.com/questions/58180/w3-total-cache-minification-breaks-wp-localize-script](http://wordpress.stackexchange.com/questions/58180/w3-total-cache-minification-breaks-wp-localize-script) * And * [http://wordpress.org/support/topic/plugin-w3-total-cache-javascript-auto-minify-wp_localize_script?replies=8](http://wordpress.org/support/topic/plugin-w3-total-cache-javascript-auto-minify-wp_localize_script?replies=8) * Plugin Contributor [Jason Crouse](https://wordpress.org/support/users/coolmann/) * (@coolmann) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-slimstatparams-is-not-defined/#post-3382815) * The handle is wp_slimstat: * ``` wp_register_script('wp_slimstat', plugins_url('/wp-slimstat.js', __FILE__), array(), self::$version, true); wp_enqueue_script('wp_slimstat'); // $params is defined and populated wp_localize_script('wp_slimstat', 'SlimStatParams', $params); ``` * [pepe](https://wordpress.org/support/users/pputzer/) * (@pputzer) * [13 years, 4 months ago](https://wordpress.org/support/topic/error-slimstatparams-is-not-defined/#post-3382816) * Yeah, I don’t use W3TC minify for JS files because I had some problems in the past. I’ve added `wp_slimstat` as an exempted file and now my scripting works again. Visits are tracked again in “Spy View”, but not in the “Right Now” tab. The result of the wp-slimstat-js.php call is a four digit hex code, does that seem right?
