I would suggest you start first with getting all the DB code out from the middle of your HTML. At the least create functions and then test each one and make sure they return what you expect them to. Then call the functions where they are needed. You have way too much duplicate code.

What debugging have you done so far? How far through the code does it get before it stops doing anything? I can’t see any code to handle what happens if the user_id doesn’t exist. If you view the source of the html page in your browser, is there anything else there?

You’ve turned off error reporting. That’s not a good start.

Where’s the bit of code that’s supposed to remove the loader?

6

Look for missing parentheses () in the foreach statement on sidebar.php.

foreach($results as $row){
7

So, as others have alluded to, learn to do some debugging. When I loaded the page and viewed the page source looking for errors I didn’t see any, but what I also didn’t see was much of the page. I commented out all queries on the dashboard page and full page still didn’t load. Once I commented the includes for header and sidebar the page loaded. I questioned the query on the sidebar page and even printed out $results and saw the expected query results. It was then, OH! there’s the problem when I looked the foreach. So the point is to figure out the point it stops working and fix the issue.
