Error 1197476758 in sync using webDAV

I use to sync web pages sync in Zotero. It used to function well half a year ago.
But recently when I sync Zotero with again (because allocates 5 GB to free account), I keep encountering the following errors:

Are these errors caused by my saved files or by Thanks in advance for assistance.

  • Those first errors should be fixed in Zotero to display proper messages, but they just indicate that is returning an error. The 409 error means is returning an HTTP 409 Conflict error. You'd have to figure out why—maybe you're over your storage space or some other limit.

    I was using mydrive for awhile. I had no syncing issues while using it, but it doesn't work if your storage folder is larger than 100MB.
