Add Product, Page Disappears

What bug (or what could be commented out) would cause the category listing page to disappear when a product is added to the section?

View web site by clicking here

If you view the source for that link there is a <!-- around line 8.

I do not see where this ends.

That <!-- is the starting tag of an HTML comment. Is that interferring with the display of the page?

Did you try to turn on the Classic Template to see if this is template releated?

UH OH! Nothing on your site now except background colors!

If you have WinMerge (get it it you don't - it's FREE!), compare your stylesheet to a fresh install stylesheet to see what's amiss!

That is weird...I didn't change anything since before I made this post?

Is WinMerge Mac compatible? I looked it up and didn't see anything about what OS it supports.

I looked into WinMerge and it appears that maybe it is not Mac friendly.
Try Ultra Compare

Hope this works for you!

I just looked at the web site (FireFox) and everything is viewable. If you're viewing in IE6 (I checked at work), it will not work, neither in IE7. I have not bothered to make it IE7 compatible yet (it will NOT be IE6 compatible at all) because I am not done working on the standards compliant coding.

So anyway, back to the original question...Why, when you click on "Air Pumps" for example, why does the content disappear?

Run the Debug Utililty to find the problem files. Available in the downloads section

I know you know - nothing shows in IE7 except the background and a bar.

To view the web site in it's current state, use FireFox.
The web site is not IE compatible yet.

Very cool, I did not know this existed.

I got four DEBUG files:

I'm not exactly sure what's wrong with this line that could possibly be causing a problem with the listing? I commented out the entire DIV and it didn't fix the problem.

Also just figured out when you click "Add To Cart" I get the same blank screen.

New error message for this?

Usually the first file listed is the problem - check it for blanks at the end of the coding.

No, I think it appears to be the same error:

What do you mean blanks? Spaces?

I don't see anything:

I switched to the classic template and the problem still exists, so it has nothing to do with my template.

Does anyone know what this problem is?

Exactly the same thing is happening to me. There is 1 product on the site and the LHS menu links bring up a blank page, though you can navigate to the product in via the new product listing on the home page. When the shop is off for maintenance I get a blank screen too and I don't think this is normal.

My debug error says:
[07-Jul-2008 08:19:40] PHP Warning: Cannot modify header information - headers already sent by (output started at /home/lbdy105a/public_html/includes/languages/english.php:1401) in /home/lbdy105a/public_html/includes/init_includes/init_templates.php on line 78

These have not been altered by me and lines 78 and 44 are empty!

Hi Stef

I just solved the identical problem! Wizzo!!

It must have been an error in modifying includes/languages/english.php as a fresh upload of the file solved the issue completely.

Charlie
:smartalec:

No, that wasn't my problem. I actually have no idea what the problem was, but I recreated my index.php file (the one I was getting those errors from) and everything worked after that. So when I was editing the other one I may have boo-booed and put something in that wasn't supposed to be there.

MAKE SURE YOUR IMAGE IS RGB!!

If it is CMYK it will stop most of the entire page loading

Huh? No one mentioned anything about it being an image problem (and in fact it isn't). Regardless, the problem is solved and it was far from an image issue.

Perhaps you caould share your soluition then.

I did.
Read post #15.

I took an original index.php file and recreated what I wanted and it worked fine.
