Solution:

When opening dxp analysis files in the Web player that contain map charts with Web Map Server (WMS)-based maps, you encounter errors similar to the one below after upgrading from Spotfire version 7.x to 10.x:

This can be due to a trailing space (a space after the URL) in the WMS URL that is used in the map chart. Removing the trailing space and saving the analysis file will resolve this issue.
