Hello all,

when clicked on configurable product PIZZA it shows error on current

Error rendering screen 
[component://ecommerce/widget/CatalogScreens.xml#inlineProductDetail]: 
groovy.lang.MissingMethodException: No signature of method: static 
org.ofbiz.base.util.Base64.base64Encode() is applicable for argument 
types: (org.ofbiz.base.util.StringUtil$StringWrapper) values: {}
