Daniel Hüsken on "[Plugin: BackWPup Free - WordPress Backup Plugin] WARNING: XML ERROR (23): EntityRef: expecting ';'"

Hi all,

I am using both WordPress and BackWPup latest versions. When I try to make a backup I got this error.

It has repeated 23 times and eventually showing '23 Waings' under status.

Why I am getting this error and how can I figure this out..?

https://wordpress.org/plugins/backwpup/

Somtimes plugin or thems filters incorectly the creation of xml files.
Try to disable other plugins and use the default theme.

Esle you can send me the xml file to d dot huesken at inpsyde dot com and i will have a look.
