Are you using the Standard Solution object or the custom one ??

Try this
  
<apex:page> standardController="Solution" sidebar="false">
<apex:form>
<apex:pageblock title="Product Details" id="ACPPageBlock" mode="edit">
<apex:pagemessages/>
<apex:pageBlockButtons>
<apex:commandButton value="Save" action="{!save}"/>                
<apex:commandButton value="Cancel" action="{!cancel}"/>             
</apex:pageBlockButtons>            
<apex:actionRegion >                
<apex:pageBlockSection title="Basic Opportunity Info" columns="1">                     
<apex:inputField value="{!Solution.CustomerID__c}"/>                     
<apex:pageBlockSectionItem >                        
<apex:outputLabel value="Product"/>                        
<apex:outputLabel >                            
<apex:inputField value="{!Solution.Product__c}">                                 
<apex:actionSupport event="onchange" rerender=" ACPPageBlock" status="Product__c"/>                             
</apex:inputField>                            
<apex:actionStatus startText="applying value..." id="Product__c"/>                          
</apex:outputLabel> 
</apex:pageBlockSectionItem> 
</apex:pageBlockSection>               
</apex:actionRegion>            
<apex:pageBlockSection title="Ratings and Reviews" columns="1" rendered="{!Solution.Product__c == 'UGC-R&R'}">                
<apex:inputField value="{!Solution.Sorting_Functionality__c}"/>

Make sure your profile is having an access  to Solution__c object if its a custom object 
Saurabh ThoratSaurabh Thorat

Hi Raj,

I'm using a custom object with the API name Solution__c

Also, I'm the System Admin and I do have access to the object
Raj VakatiRaj Vakati
Do you have access for the fields and make sure all the field API names are correct 

  
<apex:page> standardController="Solution__c" sidebar="false">
<apex:form>
<apex:pageblock title="Product Details" id="ACPPageBlock" mode="edit">
<apex:pagemessages/>
<apex:pageBlockButtons>
<apex:commandButton value="Save" action="{!save}"/>                
<apex:commandButton value="Cancel" action="{!cancel}"/>             
</apex:pageBlockButtons>            
<apex:actionRegion >                
<apex:pageBlockSection title="Basic Opportunity Info" columns="1">                     
<apex:inputField value="{!Solution__c.CustomerID__c}"/>                     
<apex:pageBlockSectionItem >                        
<apex:outputLabel value="Product"/>                        
<apex:outputLabel >                            
<apex:inputField value="{!Solution__c.Product__c}">                                 
<apex:actionSupport event="onchange" rerender=" ACPPageBlock" status="products"/>                             
</apex:inputField>                            
<apex:actionStatus startText="applying value..." id="products"/>
