Can you post a fork snapshot link?

On the upper right side of the Workspace are three buttons. One of those is fork snapshot. Click that and it will give you a link. You may have to open the link, but you may be able to right click and copy link. Either way, paste the link here.

I think you loaded the fork, not the fork snapshot. You have to click the camera icon, then either copy the link in the window or click the link and copy the url from the new browser window.

Yes, that worked. I may not have time to find the reason this morning.

Solved! In addition to the errors listed above, there are two extra semicolons:

$app = new \Slim\Slim(array(
      'view' => new \Slim\Views\Twig()  // no semicolon


$view = $app->view();
$view->parserOptions = array(
    'debug' => true // no semicolon

I used the live preview function in the free text editor Brackets. It gave me line numbers for the errors and what it thought the issue was.

Making progress, but not completely solved.

  1. You did not install slim/view. Enter composer require in the console. Then enter slim. It should be number 1 (the second entry.)

  2. Your $app = new \Slim\Slim line has the parentheses in the wrong place. It should be $app = new \Slim\Slim(array(

  3. You send the router to index.html, but it does not exist. It should be about.twig. BUT, this is not the problem. You would get Slim errors, not the white screen of death.

  4. You do not have ->name('home') after your render command. Again, this is not your core problem. Slim is not running from your commands. I copied my functioning code from this program and it ran properly, so the installation is working after the slim\views installation.

  5. If you put echo lines throughout your code, you will find that they stop displaying as soon as you try to call slim.

I will try some more troubleshooting, but I am not sure what else I will find. I tried to go line by line and copied valid code to check and it worked. One person had a problem where a character looked like a hash (#) but was actually a different character, which screwed up the code and was impossible to see.
