Troubleshooting / Common Issues – Random Letter Generator
1️⃣ Letters Not Appearing After Clicking Generate
This usually happens when the allowed letter list is empty.
Check if:
• You selected both uppercase and lowercase OFF
• You excluded all letters (A–Z)
• Your browser JavaScript is disabled
2️⃣ Animation Not Working
If the rolling/spinning animation doesn’t show:
• Ensure you didn’t remove the CSS animation classes
• Check that no JavaScript errors appear in the browser console
• Some old mobile browsers disable animation to save battery
3️⃣ Exclude Letters Not Applying
Make sure the exclusion input contains letters only (A–Z). Numbers, punctuation, or spaces are ignored and may cause unexpected behavior.
4️⃣ Uppercase or Lowercase Not Working
If letter case does not change, verify that:
• At least one checkbox is selected
• The script file is loaded only once (duplicate scripts can override behavior)
5️⃣ Mobile Browser Freezing
Some low-end devices may struggle with fast animations and multiple letters.
Try generating fewer letters (5–10) or disabling animations temporarily.
6️⃣ Duplicate Letters Showing
This is normal when generating multiple letters—each draw is independent, just like rolling a dice multiple times can repeat numbers.
7️⃣ Page Loads Slowly
This can happen if too many history items or animations remain in the DOM. Refreshing the page clears the session and restores performance.
8️⃣ Why Some Letters Never Appear?
If a letter seems missing, check:
• It is not excluded
• Both cases are not turned off
• You didn’t manually modify the letter list
