Blank screen on some pages

[Guest]

Hi all,

 

After I installed my shopping cart files to a new server (plesk panel), I started to notice some problems on some of the pages.

 

1. When I tried to login it redirects me to a black screen/page.

2. When I tried to click "add to cart" button to order it also redirects me to blank screen.

 

This was not happening on my former hosting company (godaddy.com). What might be causing this? Your help is greatly appreciated as i need to fix this before weekend :(. Thanks in advance.

 

 

Regards,

Dennis

Does this something to do with session?

 

On my former server I set configure.php store session to: define('STORE_SESSIONS', '');

 

Now on the new server forces me to use mysql: define('STORE_SESSIONS', 'mysql'); because it will cause error that it cant find /tmp folder if i leave it blank. Any help is appreciated.

 

 

Thanks,

did you have a SHARED SSL on there? Seems that the issue are with pages that would normally be SSL enabled.. the blank usually just means that you have error reporting turned off and you should go to your host and get that on so you know the exact error.

Hi Lindsay,

 

Thanks for the tip and quick reply. We are currently using a dedicated server so I think I can make it turn on. I'll get back here when I find some errors on it.

I think we use a shared SSL on this server since we have an existing customize cart installed in it w/c is working. Is shared ssl causing this problem?

 

This is the troubled cart: https://216.139.218.196:8443/sitepreview/ht...nlinestore.com/

 

But this I installed a new oscommerce catalog on here: https://216.139.218.196:8443/sitepreview/ht...re.com/catalog/ and click on "add to cart" and it seems to be working fine.

 

Also is it possible to display error using php script? what file?

I tried displaying the error at products_new.php and this is what i got...

What might causing this? It didn't appear on the old server. :huh:

I made changes by clearing out/deleting some white spaces of the files involved and it seems working now. Thanks to Lindsay for the reasons/tips behind "blank screens" :)

 

Best,

ahh the HEADERS ALREADY SENT is almost ALWAYS blank spaces before the first or after the last php tags
