I desperately need some help getting a Home Page fixed after updating to the newest 5.7 version.

The page was working fine before the update but afterwards I can't access the content and instead am getting the following error..

An exception occurred while executing 'SELECT t0.issID AS issID1, t0.customClass AS customClass2, t0.backgroundColor AS backgroundColor3, t0.backgroundImageFileID AS backgroundImageFileID4, t0.backgroundRepeat AS backgroundRepeat5, t0.backgroundSize AS backgroundSize6, t0.backgroundPosition AS backgroundPosition7, t0.borderColor AS borderColor8, t0.borderStyle AS borderStyle9, t0.borderWidth AS borderWidth10, t0.borderRadius AS borderRadius11, t0.baseFontSize AS baseFontSize12, t0.alignment AS alignment13, t0.textColor AS textColor14, t0.linkColor AS linkColor15, t0.marginTop AS marginTop16, t0.marginBottom AS marginBottom17, t0.marginLeft AS marginLeft18, t0.marginRight AS marginRight19, t0.paddingTop AS paddingTop20, t0.paddingBottom AS paddingBottom21, t0.paddingLeft AS paddingLeft22, t0.paddingRight AS paddingRight23, t0.rotate AS rotate24, t0.boxShadowHorizontal AS boxShadowHorizontal25, t0.boxShadowVertical AS boxShadowVertical26, t0.boxShadowBlur AS boxShadowBlur27, t0.boxShadowSpread AS boxShadowSpread28, t0.boxShadowColor AS boxShadowColor29, t0.hideOnExtraSmallDevice AS hideOnExtraSmallDevice30, t0.hideOnSmallDevice AS hideOnSmallDevice31, t0.hideOnMediumDevice AS hideOnMediumDevice32, t0.hideOnLargeDevice AS hideOnLargeDevice33 FROM StyleCustomizerInlineStyleSets t0 WHERE t0.issID = ?' with params ["12"]: SQLSTATE[42S22]: Column not found: 1054 Unknown column 't0.backgroundSize' in 'field list'

I did not edit code we were simply working on some basic visual changes.. Please help so we can move forward with our website construction.
