-**Cause**: LiteMage uses ESI to hole punch certain blocks while LiteSpeed Web Server assembles the main HTML page and those ESI blocks from different responses. When hole punched blocks (ESI blocks) also contain javascript, the javascript minifier filter will process the partial HTML again, causing incompatible javascript references for the whole page.
+====Cause====
+LiteMage uses ESI to hole-punch certain blocks, which are then used by LiteSpeed Web Server when assembling the main HTML page. Each ESI block generates a separate HTTP response, and each of these responses passes through the JavaScript Minifier filter.
+When a hole-punched (ESI) block also contains JavaScript, the JavaScript Minifier filter processes the partial HTML as if it were an independent page, causing incompatible JavaScript references for the rest of the assembled main HTML page.
-**Solution**: Locate the module throwing this error, the pagespeed module in this example, and either disable it or modify it's configuration settings. For this case, pagespeed's Javascript "Enabled" setting had to be changed from "Yes" to "No".
