Please follow the instruction below:
1) Don’t forget to take a backup of the file prior to any change.
2) Open js/main.js from the parent theme and search for the following text:
textFit(jQuery(‘.exhibitors-wrapper .exhibitor-about’), {alignHoriz: false, alignVert: true, maxFontSize: 16, suppressErrors: false})
3) Just comment or remove that line and save it.
You need take a back up of this file before the upgrade, otherwise you will lose the changed files when you upgrade the theme.
