Q: What should I do if the five-star rating icons in the template for the 2.4G digital price tags system backend are not displaying correctly?
A: 1. Place the zfull-gb.ttf font file into your computer's font library. You can access this library through Control Panel > Fonts.
2. Restart the following five services: eRetail_v3.1, eRetail_v3.1_datasync, eRetail_v3.1_sendserver, eRetail_v3.1-TFTApi, and eRetail_v3.1_videoservice.
3. Afterward, log back into the system, and the template should display correctly.
