If experiments appear there, it's a caching issue. --- ## Editor Issues ### "Can't find location to place experiment" **Symptoms:** Error appears when trying to create an experiment. **Common causes:** - Element is inside an iframe - Element loads dynamically via JavaScript - Element is inside a shadow DOM component **Solution:** Try selecting a parent element, or verify the element exists in the static HTML. --- ### Prompt not working / errors **Symptoms:** AI returns an error or unexpected result. **Common causes:** - Element is dynamic (price, stock, selector) - Prompt is too vague - Element is complex (multi-nested components) **Solutions:** - Be more specific: "Make this one sentence" not "Make it shorter" - Avoid dynamic elements like prices or inventory - Try a simpler element first --- ### Mobile view looks wrong **Symptoms:** Experiment looks good on desktop but broken on mobile. **Cause:** AI optimizes for the current view. **Solution:** - Always check mobile preview before launching - Use "on mobile only" in prompts for mobile-specific changes - Create separate prompts for mobile adjustments --- ## Results & Dashboard Issues ### No data showing **Symptoms:** Dashboard shows zero sessions or conversions. **Check:** - Script is installed correctly - At least one experiment is live - Conversion goal is configured - Sufficient time has passed (24-48 hours minimum) --- ### Results seem inaccurate **Symptoms:** Numbers don't match Google Analytics. **Possible causes:** - Different attribution windows - Bot traffic affecting one tool differently - Sampling differences **Solution:** Dalton's relative comparison (variant vs baseline) remains accurate even if absolute numbers differ slightly from GA4. --- ### Significance taking too long **Symptoms:** Experiments running for weeks without reaching significance. **Common causes:** - Low traffic volume - Low conversion rate (under 2%) - Too many variants splitting traffic **Solutions:** - Reduce number of variants - Focus on higher-traffic pages - Consider using click-through rate instead of purchase for faster learning --- ## Preview Issues ### Preview looks different from live **Symptoms:** Preview link shows slow loading or different styling. **Cause:** Preview mode has additional debugging overhead. **Solution:** Right-click preview link → Open in incognito. Live visitors see instant changes (<50ms). --- ### Preview shows wrong variant **Symptoms:** You keep seeing the same variant in preview. **Cause:** Cookie persistence. **Solution:** Use incognito mode or clear cookies to see different variants. --- ## Still Need Help?
