Recent bbPress update completely broke the styling to it’s forum that was using custom styles. I fixed the issue and updated the World of Warcraft WordPress Theme V-2. The theme can be re-downloaded and installed like any other theme.
Just a note that deleting the old theme and uploading/installing new one does not affect the content, i.e. posts , pages or media. database is not touched at all.
One additional note that if you have edited styling to the installed theme directly either in styles.css or any other file like functions.php, those changes will be lost as a result of installing a new theme.
For that reason, I had included the “child theme” for the theme where you can edit the styles and functions. and is explained here: https://www.warcraftwordpress.com/child-theme-v2/
