https and http redirecting error

Hello,

In the past i used to run my site on http but later switched to https and then finally decided to use http://. I dont know but my site keeps showing this error beside I also get log off from my admin panel every now and then.

update wp_WP_SEO_Redirection set redirect_from=REPLACE(redirect_from, http://www.website.com, https://www.website.com), redirect_to=REPLACE(redirect_to, http://www.website.com, https://www.website.com)

Any help will be appreciated.

Thanks,
