Remote storage with webdav not work

Hello,

We released a new version please try updating, if issue still present, please open a separate ticket.

Closing this for now.

I encounter the same problem, even with the latest plugin version (4.2.13). The remote storage connection is verified without any problem, but uploading to it gives a red error message. Will this be fixed anytime soon?

Whenever I try a new backup manually, everything goes fine until uploading it to my WebDav server. It says:

parsererrorSyntaxError: Unexpected token < in JSON at position 0

Can you please check the XCloner logs from it’s dashboard, do you get any details on the error there? It could be that you are encountering a transfer timeout error, so i suggest in this case to setup a scheduled backup and see if that helps.

Thanks for your quick reply. I’m having this problem for something like a month already using scheduled backups. The XCloner log shows this:

I still have the same problem, even with the latest release… Any updates on this?

Still no solution for this? The Webdav connection verifies just fine, but the backup can’t be transferred… both with manual and automatic backups.

Can you describe more about what service you are using?

StackStorage WebDAV (from TransIP.nl)
It worked fine before!

Hello,

In order to investigate this we need you to provide us wordpress admin access.

Please create an admin account on your website for us, and send these details to [email protected]

Please include:

an wordpress admin user/password

Webdav required connection details.

Please before providing them make sure you have a full working website backup saved, providing them means you’ve read and understood this.

Regards

After debugging the webdav library dependency we have in place, i’ve found two issues:

1. the Webdav Base Url needs to be always without any suffixes, like https://webdav.site.com and NOT https://webdav.site.com/remote/…/
2. the Webdav Target Dir can contain the missing suffix, like remote/…/backups for instance

this should solve the “Could not rewind…” error.

The second problem seems to be related to a bug in the webdav sabre library dependency we have in place, where when a backup file is uploaded, it’s size will be zero, we have opened a issue here https://github.com/sabre-io/http/issues/153

I’ve posted the fixes in our dev package here https://github.com/watchfulli/XCloner-Wordpress/archive/milestone4.2.16.zip , feel free to let me know if you have anymore issues

@ovidiul, the fix works great! Thank you so much!

After updating to 4.2.16 I can have https://USERNAME.stackstorage.com/remote.php/webdav/ as WebDAV Base Url and BACKUP/Wordpress as WebDAV Target Path without any errors ??
