Check errors when adding or editing products.

1. You receive a duplicate custom product code error If you enter a custom product code when adding a product, the system will block the process if the code already exists. If you're sure there's no product using the same code, go to Products > Product List > Removed Products to check for any deleted items using that code.

   Make sure to Permanently delete the existing product before reusing that custom code.
    

2. Korean characters break in URLs when switching to code view in the new editor
   · This is due to security encoding (to prevent XSS vulnerabilities). URLs containing Korean characters are automatically encoded. It is not possible to disable this behavior. ·

    

3. When editing a product, a red banner appears saying the product is being edited in another session This is a feature to prevent concurrent edits within the product edit popup.
   It may appear if you're working in multiple windows/tabs on the same PC, have duplicate admin sessions, or a previous edit session was closed without saving.
    

   Caution

   If you see this banner, your changes may not be saved. Please click Save to refresh, close all browser windows, and reopen the page to ensure the banner no longer appears before continuing with edits.
    

4. The legacy editor appears when uploading product detail images The current editor uses base64 encoding for images. If the encoded image size exceeds 100,000 bytes, the system will automatically switch to the legacy editor (NN). 
    
5. Discount benefits do not appear in the preview even after setting them
   Discounts do not show in the preview according to the current system behavior.
