fjavier on "[Plugin: WordPress SEO by Yoast] No meta description for date archives"

Hi,
I was trying to look for a relevant topic already resolved but without luck and in order to take some precautions I was wondering that if in order to correct my issue and if I need to deactivate the latest version to install the developers version will this remove all my settings and items data? or the export feature will take care of this?
Thanks in advance
