robot.cfg has
<plugins>
   <attr_publisher>
     pluginPath = plugins/attr_publisher/attr_publisher.dll 
     pluginName = attr_publisher
     configPath = plugins/attr_publisher/attr_publisher.cfg
     configSection = variables
     active = 1
   </attr_publisher>
<plugins>
</controller> 
Cause:
This is related to application discovery.

The <plugins> section of robot.cfg does not need to be removed.  The plugins section is created when you deploy application discovery profiles in MCS, the problem is that MCS and the robot don't agree on how to create it.  7.93HF5 is fixed to make it agree with MCS.  the section should be there, but the errors will go away
Resolution:
This is fixed in Robot 7.93HF5 or later. This can be downloaded from the UIM Hotfix Page
