When i create a brand new visualforce page in the salesforce admin and attempt to view the page, i get the following error:
"This site can’t be reached.’s server IP address could not be found."

When i click on the security link next to the visualforce page, all profiles are enabled.

Here is the VF code:
<apex:page sidebar="false" showheader="false">

I discovered the root cause of the issue. An installed package (with a blank namespaceprefix) was uninstalled and caused the blank namespaceprefix URL ( on visualforce pages to no longer work.
I resolved this by installing a new package with no namespaceprefix and a dummy file. This seemed to re-enable the blank namespaceprefix.

We have a few installed app packages in our full-text sandbox environment in various stages of testing. We're moving toward final stages of deployment for one of them, which will require a refresh of the full-test sandbox to match our current production org.

1) Is there a good way to transfer the other installed apps/settings to another sandbox? (Or do I need to re-install onto the other sandbox and recreate the fields/formulas/settings on their own?)
2) Would you recommend using a partial copy sandbox or a developer/developer pro sandbox? I haven't used developer/developer pro sandboxes, but I don't know if they will contain enough features/object data to do the proper testing on these apps. [Apps include roll-up helper, data quality dashboards, conga]

@Julian: AppExchange apps should be installed into production directly from the AppExchange.  They cannot be promoted from sandbox using deployment tools.  This is true for both managed and unmanaged packages.
However, after you install an app in production you can migrate your customizations and extensions from sandbox.  The IDE doesn't let you download or edit managed components, so the Migration Tool for Ant is your best bet when migrating these components.

What is the process of listing an app on appExchange.

Hi Saurabh, Ive never heard of this type of agreement. I am considering venturing partnership as both ISV and Consultant with Salesforce. I recently acquired an LLC filing status. A legal partnership is considered an "incorporation" - that which requires organizations to have a limited partnership, not for profit, or limited liability company, S-corp. I've been where you are and know there are steps involved to get to the eligibility stage. Even if the app is free, i believe there is a protocol in place to ensure proprietary rights and other business laws are adhered to.
Go to this link: .. Scroll to the bottom and select the Join Now! button. Fill out the form and wait for a SF Partner rep to get back so you can schedule time with them to discuss your goals.

Can you let me know how to hide a section in visualforce page onchange of picklist value?

The rendered attribute in a page block section needs to get a true or false. If you have a straight forward condition, you could write something like as shown below.
<apex:pageBlockSection title="Test" rendered="{!Account.industry == 'IT'}">

If you have a standard controller with an extensions class OR a custom controller in your visualforce page, you could write your section code in visualforce page as 
<apex:pageBlockSection title="Test" rendered="{!CheckMe}">

You method in the controller would look like
public Boolean CheckMe {
  get {
   Boolean chk = true;
   chk = chk && (acc.industry != 'IT');
   return chk;

Hope this helps.
Please do mark this as the answer if this solves your issue.

I wrote a class 
public with sharing class SlackOpportunityPush {
    // To publish Opportunity values in form of a String//
    public static final String slackURL = '';
    public class Oppty {
        @InvocableVariable(label='Opportunity Name')
        public String opptyName;
        public String Owner;
        @InvocableVariable(label='Opportunity Amount')
        public String Amount;
        @InvocableVariable(label='Account Development Owner')
        public String AccountDE;
        public String Account;
    @InvocableMethod(label='Push to Slack')
    public static void postToSlack(List<Oppty> oppties) { 
        Oppty o = oppties[0]; // If bulk, only post first to avoid overloading Slack channel
        Map<String,Object> msg = new Map<String,Object>();
        msg.put('text',  '\n Opportunity Won !  Congrats to Opportunity Owner !  :-  ' +o.Owner +   '\n and Account Development Owner:-  '+ o.AccountDE + '\n who just closed Opportunity:-  ' +o.opptyName +   '\n associated to Account:- ' + o.Account +'\n for Opportunity Amount:- $ ' + o.Amount);
        System.debug('Called msg.put');
        System.debug('OpportunityOwner '+o.Owner);
        System.debug('OpportunityAccount '+o.Account);
        System.debug('OpportunityAmount '+o.Amount);
        String body = JSON.serialize(msg);    
        System.enqueueJob(new QueueableSlackCall(slackURL,'POST',body));
    public class QueueableSlackCall implements System.Queueable, Database.AllowsCallouts {
        public final String url;
        public final String method;
        public final String body;
        public QueueableSlackCall(String url,String method,String body) {
            this.url = url;
            this.method = method;
            this.body = body;
        public void execute(System.QueueableContext ctx) {
            HttpRequest req = new HttpRequest();
            Http http = new Http();
            HttpResponse res = http.send(req);

Test class 
private class SlackOpportunityTest {

static testMethod void testpostToSlack() {
SlackOpportunityPush.Oppty opt = new SlackOpportunityPush.Oppty();
opt.opptyName = 'Unit Test Opt';
opt.Owner = 'Unit Test Owner';

List<SlackOpportunityPush.oppty> lis = new List<SlackOpportunityPush.oppty>();

System.assertEquals(lis, lis); 

Now while Deploying I get this error :

​Methods defined as TestMethod do not support Web service callouts

Hi Hormoz,

You will have to use callout mock intefaces to test classes making http calllout.

Yes, I think the controller which is associated with the vf page checks for the logged in user's profile and then redirects the page.

Is the package you installed unmanaged or managed ?

If it's unmanaged, the code can be looked into and changed. If its managed, read through the User/Installation Manual properly. There must be something written about this.

If nothing helps, reach out the the makers of the package regarding this.

Let me know if you need any further help on this.
