Yesterday, I opened Zotero and successfully scraped more than 10 academic papers from web pages, and I also revised the categorization in "My Library". I never closed Zotero afterward, but when I shut it down and restarted my computer today, all the papers I’d scraped the day before and the changes I’d made to the categorization in "My Library" were gone. The content in Zotero reverted to its state before I opened the software yesterday. What should I do to fix this?
