Losing things do to a glitch/website error sucks for website owners, especially if they act as their first line IT specialist. Always bad to lose recent data. Maybe backing up the shop portion of the site daily, if possible, might be a good idea. What happened really doesn’t matter to those who read the forum for fun and entertainment. I can always repost my recent builds. But to the site owner with a “store” really hurts and means a lot of work.
This just reminds me to fix problems with the back-up software (auto mode) I have on my own PC.
