I have just started using Logseq yesterday and installed it on my macbook. So far I worked on one page for a couple of hours…whilst highlighting literature in logseq suddenly an error occured - I quit logseq and opend it again, and had to realyse that my logseq page was compleatly empty - no pages, no notes - everything gone. I saved the mc. fils on my desktop and they are still there but logseq can’t open them…what should I do? please help!
