Directory Paths: Make them portable
I understand messages like this can be worrisome but the msg actually tells you exactly what you need to fix the problem, eg it is suggesting you replace what you currently have set as the paths with the tokens shown. Try clicking on the 'Directories' link and then reading the help message that you will find there. If you need more help then paste a screenshot or the string in the 'paths' that you currently have, and someone will help coach you through which bits to replace with eg [cms.root]
