This afternoon when I was logging into my lab computer, my Firefox was crashed. I restarted it, and I found my Zotero could not show my data in its all panels: both in collection and in main entry panel. All were blank. I then created a new Firefox profile and copy my Zotero data to a new space and I connected this new copy to my Zotero installed in the new Firefox profile. After entering my DAV server which is in box.net, I could not connect to it. The error message was related to certificate or what, I forgot. But I knew, my dav server was ok, because when I browsed it via the browser, I could connect via my account. I repeated by creating another new Firefox profile, it gave the same result.
I Googled and, after quite a long hour, I got another advice to restart the computer. I restarted the computer, and open my old Firefox profile, and it worked. Zotero worked again.
It seems this trouble relates to my networked computer, right? In my "Local Area Connection" status, Number of bytes in sent and received activity grows very fast, and I still don't know the work around of this anomaly. But when I have spare time in the future, I will restore my system to my old copy of the windows system that I have the backup for it. I hope doing this may recover this problem. But as usual, before restoring to old version, I will need to back-up my troubled system. I use free version of Macrium Reflect to do these jobs.
