Add to cart generates a blank page

I'm part way through a new site and have a strange thing happening. When I click the add to cart button the site generates a blank page, looking at the page source shows nothing there as well. Clicking the back button on the browser takes me back to the product page which has the green product added bar on top and when I go to the cart the product has been added.

I am following the standard override system for the template. I find if I change back to classic green the site works ok. I have obviously done something. My first check was restoring the tpl_product_info_display.php but this didn't help.

Can anyone give me a clue to what file I may have corrupted.

The site is http://evisualbridalboutique.com/store

Thanks in advance

Have you tried the Debug Error-Logging Utility?

Hi Steven,

Thanks for that handy hint, I'm going to give it a go.

I found the problem, it was caused by having an override directory in the languages folder with english.php. The system was reading this file but didn't like it there. I removed the override directory and the site went back to normal.

Thanks for the debug tip, found the problem in 5 minutes.

No probs. Pleased you got it fixed.

I've got the same problem again, it happens when you either try to add to the shopping cart, log in or goto the checkout. There may be some other places that I haven't found. The site was working ok until I added the Zen Lightbox utility.

This is the output from the debug log,

[12-May-2008 23:21:32] PHP Warning: Cannot modify header information - headers already sent by (output started at /home/evisualb/public_html/store/includes/languages/english.php:1401) in /home/evisualb/public_html/store/includes/init_includes/init_templates.php on line 78

does anyone have any ideas?

This should help:

Hi Steven,

You're a legend!

It was a space at the end of the english.php file, it seems that was the problem all along. I was getting worried.

Thanks again,

Joe

Hi,

thanks for this post, I was scratching my head on this one!!

I had 2 blank lines at the end of english.php after the closing '?>', I removed them and all works fine, thanks again

Alan

Great! Good job.

This just fixed my problem too...restored my backup english.php and it fixed the problem......added each tweak and uploaded after until I got it resolved. Thanks for sharing/asking/assisting...great forum!!

Steven you are my man! Thanks for the tip.

By the way I hate the extra lines problem of PHP. If somehow a few extra blank lines are added to bottom of a PHP page, it results in stupid errors. How very nonsense for such an old programming language.

I cannot seem to locate the problem. This problem is fairly new, I just started having it. Here is the message I get:

[09-Feb-2011 14:59:23] PHP Warning: include_once(includes/languages/english.php) [<a href='function.include-once'>function.include-once</a>]: failed to open stream: No such file or directory in /home/london/public_html/allclipart.info/shop/includes/init_includes/init_templates.php on line 72

Can anyone help me?

It's telling you that your english.php file isn't able to load because it's not found.

I am getting this same blank page error. I opened the log files but don't know where to begin as there are so many of them. Any guidance?

More details...When I log in as a customer and add the products, I get a blank page, but when I check my shopping cart (I have to go back a screen in the browser) the items are all there.

See: https://www.zen-cart.com/tutorials/index.php?article=87

Line 17, extra spaces at the end removed and problem solved!!!

Can't begin to say how much I appreciate this!

I'm having the same issue. I've removed the blank spaces and my line 17 is blank. After I add a product to the card I get a blank screen. http://www.jennifershon.com/store/index.php?main_page=product_info&cPath=138&products_id=475&number_of_uploads=0&action=add_product

Everything was working until I did the dns and replaced the temporary url with the real url.

Here's the error message
