Question

Blank pages on Zen Cart

Asked by: mel200

Hi- I am installing a cart on this site, it's in develpoment right now. I have deleted the whole installation of zen cart on diabeticmealprograms.com, then reinstalled it. I carefully make changes to these files:

cart/includes /languages/english.php

cart/ Includes/languages/english/classic/header.php

cart/includes /languages/english/index.php

 I also make changes to layout boxes controller, banner manager and define pages/main_page in the administrator. After I make each change, I check to be sure I can add a product to the cart, and I save the original of each php file. After making a change to index.php, I ran into the issue again of not being able to add an item to the cart or I get a blank page. (I also get the blank page if I try to log in, although if I then restart and go to cart, I am logged in. Same thing with adding an item, the item is added, but all I see is a blank page.)

 I went back and uploaded the original cart/includes /languages/english/index.php. I confirmed it is there, but I'm still seeing blank pages.

Did you setup Zen Cart with Site Security without a certificate?

Meaning you set the option stating you had it but you do not?

 

by: mel200Posted on 2008-09-23 at 10:49:05ID: 22552055

I never set that option, but that doesn't mean it's not in place. Where do I check that? Thanks!

 

by: KnightsmanPosted on 2008-09-23 at 11:23:42ID: 22552392

see if the link works at the beginning url with htts:// instead of http://

Would probably only give you a problem if you set it as secured and you dont really have it.

You might want to reinstall and start from scratch and create a custom layout.  
check out this site: http://tutorials.zen-cart.com/index.php?article=142

Let me know if im not understanding your question correctly.

 

by: mel200Posted on 2008-09-23 at 11:43:54ID: 22552591

Yeah- I didn't explain it clearly, I guess. Let me try again.  I installed a fresh version of Zen Cart, added a product and it worked. Then I started making changes. As I modified a file, and uploaded it, I saved a backup of the original. I tested each time I uploaded a new file (refreshing CTRL F5 each time, and making sure the changes were there). I added the product to the cart, and if it worked, I would modify another file. It was after changing index.php that I couldn't add to the cart. I uploaded the original, and the problem was still there. I went back and uploaded the other originals, and the problem's still there.

 

by: KnightsmanPosted on 2008-09-23 at 13:03:22ID: 22553431

auuuhh, i understand now.  I had the same issue because I tried to move the file, and the manual on the site didnt work for me.  

Try this, its a debugger log for zen cart: might help..

Also, you might want to check out this page.  Talks a lot about "blank pages".

Let me know if any of this helps!

 

by: mel200Posted on 2008-09-23 at 13:58:44ID: 22554009

Thanks-I'll try that debugger!

 

by: mel200Posted on 2008-09-23 at 14:06:52ID: 22554086

OK- Here is what I get:

[23-Sep-2008 15:02:57] PHP Warning:  Cannot modify header information - headers already sent by (output started at /home/diabeti7/public_html/cart/includes/languages/english.php:1401) in /home/diabeti7/public_html/cart/includes/init_includes/init_templates.php on line 78
[23-Sep-2008 15:02:57] PHP Warning:  Cannot modify header information - headers already sent by (output started at /home/diabeti7/public_html/cart/includes/languages/english.php:1401) in /home/diabeti7/public_html/cart/includes/functions/functions_general.php on line 44

So I'm thinking I should replace cart/includes/languages/english.php with the original. Sound right to you? :)

 

by: mel200Posted on 2008-09-23 at 14:11:08ID: 22554133

argh. Replaced english.php, no change.

 

by: mel200Posted on 2008-09-23 at 14:12:49ID: 22554155

sorry- should have included the new log:

Thanks very much-I will look at it. Meanwhile I have uninstalled and reinstalled again. :)

 

by: mel200Posted on 2008-09-24 at 08:10:49ID: 22560526

That could be the answer! I'm having the same issue on another site that I'm testing, I'll try the debugger there and see what I get. Thanks again!

 

by: mel200Posted on 2008-09-24 at 08:24:49ID: 22560679

you are my sunshine, my only sunshine..... that was it! A space after ?> in english.php. My guess is that it was put there by dreamweaver? Is dreamweaver something I shouldn't use with php files? Anyway, I'll award the points, thanks a million.

 

by: mel200Posted on 2008-09-24 at 08:25:43ID: 31499348

Used the debugger suggested, then followed up with the solution provided.  Problem solved! Thanks.

 

by: KnightsmanPosted on 2008-09-29 at 10:29:50ID: 22598568

Far as I know dreamweaver and PHP work good.  Prolly just a glitch with Zen Cart!  Thanks for letting me be your sunshine!!  :)  Glad you got it working
