Shopping Cart won't open - error began after Security Patch installed

[starmakersandy]

This is the site where I’m having the problem.

www.asylett.com/authorOrdering
version 1.3.8

When you add an item to the shopping cart you get a blank screen with this URL:
http://www.asylett.com/authorOrderin...r_of_uploads=0

If you reinvoke the main catalog URL above, you’ll see the Shopping Cart box on the side showing your item is in there, but when you click on the box you get another blank screen with this URL:
http://www.asylett.com/authorOrderin...=shopping_cart

The problem all started when I tried to install the security patch. The entire store refused to open after I installed the patch. All I could get was a blank page with the URL at the top suggesting the site was opened. I can’t remember the URL exactly, but it ended with mainpage=

I reread the instructions and retraced my installation of the security patch to make certain I’d done everything correctly. I had. Still it didn’t work. So, according to the instructions, I took it all out and replaced the altered files with the backup files I had of my original site.

Still, nothing. Same blank page when I tried to open the catalog.

I finally gave up and replaced all the files with my backup files and it appeared to be working. At least the main page is coming up and I can get to the individual product pages. BUT the shopping cart error persisted.

I tried loading my shopping cart file from my other online store site where it is working fine (www.asylett.com/asylettzstore/) I performed the same “exchange” back in 2008 as evidenced in a message to the forum, and the problem was resolved then...but not this time. I’m still getting the same blank shopping cart error.

Any ideas on where else to look? Thanks in advance,

Sandra,
This is usually a result of putting a file in the wrong directory. Go back through the patch(es) and make sure you've put the files in the correct directory.

I am having the exact same problem! Does anyone have any ideas what the problem could be or how to fix it? I am not a Zen Guru by any means.

Help!

Thanks...

I can get to your site but get a blank page on adding products ...

Get the Debug Tool from the Free Software Add Ons ...

Also check that you installed the Security Patches correctly ...
http://www.zen-cart.com/forum/showthread.php?t=131115

Specifically, make sure that the right html_output.php file is in the right directories:
/includes/functions/html_output.php
/admin/includes/functions/html_output.php

these files are different inside and you will have problems if you mix them up ...

Hi Ajeh,

Thanks for the reply! I followed your instructions. Here is what the debug gave me:

[10-Oct-2009 23:40:56] PHP Warning: Cannot modify header information - headers already sent by (output started at /home/earphone/public_html/includes/languages/english.php:1401) in /home/earphone/public_html/includes/init_includes/init_templates.php on line 78

Any ideas?

Thanks!

The message is telling you there's a problem on line 1401 of english.php
See this related FAQ, which I found by searching for the error message "headers already sent": https://www.zen-cart.com/tutorials/index.php?article=87

Thanks. I opened the english.php, but I don't have a line 1401. Mine ends at 1397.

Any suggestions?

Thanks!

Were you checking the file *on the server*?
Did you try replacing the english.php file on the server with the original version of it?
Did you try removing the ?> from the end of the same file?

That did it! Removing the ?> worked! Now, for a newbie, what did I do to fix it and how can I prevent this from happening in the future?

Thanks!

Evidently when you edited your english.php file your editor must have left one or more blank lines after the closing ?>
Since that file processes very early, long before content is supposed to be sent to the browser, and those blank lines *get* sent to the browser, those lines were causing a problem with the normal order of operations.
That's "why".

Solution: don't leave trailing blank lines around if they're outside of the <?php and ?> marks in the file.
