Token Text in state EndRootElement would result in an invalid XML document

Problem:  After migrating our solution from SharePoint 2010 to SharePoint 2013 we found an error related to custom XSL file.
The XSL itself was well formed and the generated XML also was fine but we had the below error
"Token Text in state EndRootElement would result in an invalid XML document. Make sure that the ConformanceLevel setting is set to ConformanceLevel.Fragment or ConformanceLevel.Auto if you want to write an XML fragment."

Root Cause:

Solution: After investigation I had found that there's a problem might occur in XSL with SharePoint 2013 related to referencing Javascript tags inside XSL.

Hope it helps you.

The media set has 2 media families but only 1 are provided

Issue

While attempting to restore your database using MyLittle Backup you receive the following error:

"The media set has 2 media families but only 1 are provided"

Cause

This error is due to your backup being divided into more than one part at the time of creating your initial backup file. The backup will need to be repeated so that it is contained in one file only.

In the example screenshot below you will see that there are two paths listed for the backup destination, which will create a backup over two files.

Resolution

Remove one path from the backup destination so that only one .bak file is created and then restore this file using MyLittleBackup.

You can know more details about the issue from Microsoft PM who owns SQL backups
