# Fix caching plugins breaking analytics

> Stop WP Rocket, LiteSpeed Cache, Autoptimize, Cloudflare Rocket Loader and other caching or optimization tools from breaking the analytics tracker script.

Page caches and "optimize JavaScript" features can:

- serve old HTML without the snippet: **purge the cache** after adding it,
- **combine or minify** `pa.js` into a bundle. The tracker reads its own
  `<script>` tag (`document.currentScript`) for `data-site` and the other
  attributes. Inside a bundle there's no such tag and it does nothing,
- **delay JavaScript until user interaction**: visitors who don't
  interact are never counted, and time on page is wrong,
- rewrite or strip `data-` attributes.

## Fix

Exclude `pa.js` (and `privatusanalytics.com`) from combine, minify, defer/delay and
lazy-load features. Common settings:

| Tool | Where |
|---|---|
| WP Rocket | File Optimization → *Excluded JavaScript Files* and *Delay JavaScript execution → Excluded*: add `pa.js` |
| LiteSpeed Cache | Page Optimization → JS Settings → *JS Excludes* and *JS Delayed Excludes* |
| Autoptimize | JS Options → *Exclude scripts from Autoptimize*: add `pa.js` |
| W3 Total Cache | Minify → JS → *Never minify the following JS files* |
| Cloudflare Rocket Loader | Add `data-cfasync="false"` to the script tag |
| Perfmatters, NitroPack, SiteGround Optimizer | Their "exclude from delay/combine" lists |

With Cloudflare Rocket Loader:

```html
<script data-cfasync="false" defer src="https://privatusanalytics.com/js/pa.js" data-site="pa_YOURSITEID"></script>
```

Then purge all caches and check the page source again.
