Some times wordpress can break due to improper permissions.
In order to fix permissions and ownership of the wordpress directories you need to run a few commands. We reccomend using your ssh command line to execute this.
From your html directory where you are hosting your word press website. you need to first dictate to apache who the owner of the directories and files are.
In CentoOS you would run
chown -r apache ./
If you are using Debian then you would run
chown -R www-data ./
then set the file and folder permissions
find -type d -exec chmod 755 {} \;find -type f -exec chmod 664 {} \;
