Environment Setup

To ensure accurate tracking and smooth performance with QA Advisor, we recommend adjusting the following server and plugin settings.

1. JavaScript Compression & Minification​

Do not compress, minify, or combine JavaScript files used by QA Advisor.
Some optimization plugins or themes may interfere with tracking scripts by modifying or delaying their execution.

✅ Check your caching or optimization plugin settings
✅ Disable JS minification or defer/async for QA Advisor scripts

For more technical background, see When jQuery is Deferred.

2. PHP Memory Limit & Execution Time​

QA Advisor processes tracking data during daily aggregation, which can be memory-intensive on larger sites.

We recommend the following PHP settings:

  • memory_limit: 1024M or higher
  • max_execution_time: 240 seconds or more

💡 These settings can usually be adjusted via php.ini, .htaccess, or your hosting control panel.
If you're unsure, ask your hosting provider.

3. Plugin & Theme Compatibility​

QA Advisor works with most major plugins and themes. However, we recommend:

  • Disabling JavaScript defer/async for critical scripts
  • Ensuring your caching plugin allows output from qa-heatmap-analytics
  • Avoiding duplication with other tracking tools that modify global events

4. CDN & Server Migration​

If you're using a CDN (e.g., Cloudflare) or recently migrated your server:

  • Clear all caches (browser, plugin, CDN)
  • Confirm that QA Advisor scripts are not blocked or delayed
  • Make sure your server time zone is correct (used for data grouping)

5. Optional: Confirm Script Output​

To verify that the tracking script is being correctly loaded:

  1. Visit your website while not logged in
  2. Right-click and choose “View Page Source”
  3. Search the HTML for qahm or qahmz

If these strings are not found, the script may be blocked or not loading.
Check for JavaScript errors or plugin conflicts.
