No Output - Fresh Installation

Postby PeteST » Wed Jan 04, 2012 4:56 am

Hi,

I recently installed AlegroCart in order to develop a payment module. I was able to install the software correctly and get quite far into development but I have turned my development machine on this-morning and Alegro cart is not running correctly. When I attempt to access the store homepage or the admin homepage (after logging in; I am able to login) then a white screen - no output - is displayed. Furthermore, the page is taking much longer to load. Close to 30 seconds, perhaps.

I have reinstalled AlegroCart (with a new database) numerous times now, thinking that I must have corrupted something inadvertantly, but am still getting this problem. The Apache error log says nothing and the access log gives me a 200 status for the requested page. The AlegroCart logs are empty and no PHP warnings are displayed (error_reporting is set to E_ALL | E_STRICT and display_errors is set to 1 both locally and globally).

I attempted a little debugging and found that it was the controller's dispatch() method that was causing the delay. See the two excerpts of code and their output below:

function dispatch(&$request) {
$action = $this->requestHandler($request);
var_dump($action);echo 'a.<br>';

array(2) { ["class"]=> string(4) "home" ["method"]=> string(5) "index" }

function execute($action) {
var_dump($action);

array(2) { ["class"]=> string(11) "maintenance" ["method"]=> string(16) "CheckMaintenance" } array(2) { ["class"]=> string(4) "home" ["method"]=> string(5) "index" }

I'm not sure if that well help. Am I missing something painfully obvious? Any advice you can offer would be great. Thank you.

PHP 5.3, Apache 2.2, XAMPP installation running on localhost.

Edit: I just tried in another browser (Opera 11.52) and it displays correctly. This makes no sense, since I was developing on Firefox 8 yesterday with no problem.

FF8.0 behaves sometimes very interesting. I kindly suggest you to upgrade to 8.0.1. That is OK.
Brent has run into a cache problem during the new session handler development and reported FF.

I am curious.
When you did your dump, what where the arrays you got in the 2 functions.

And yes, as Leo pointed out, I had issues developing the new sessions class with Firefox.
The cache systems in Firefox 8.0 and previous has bugs. It screws up Javascript as well. I had Issues with the new CKeditor as well. Clear the cache and you should be back to normal.

Hi,

Thank you both for your replies. Clearing the Firefox cache did resolve the problem.

Just so you are aware, I have also encountered this issue in Opera 11.52 (but not, it seems, as frequently).

Brent: I am afraid that I've since removed all debugging calls that I added so I can't give you the information you are after!

Thanks once again,

Peter
