| - | **Cause**: Some modules minify JavaScript, which may cause the JS error "jQuery is not defined" | + | **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 is a different HTTP response and each of these responses will pass through the minify filter. When a hole punched block (ESI block) also contain javascript, the javascript minifier filter will process the partial HTML again, causing incompatible javascript references for the whole 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". | **Solution**: Locate the module throwing this error, the pagespeed module in this example, and either disable it or modify it's configuration settings.
