Thumbnails being deleted!

[Guest estelle]

Hey everyone,

I'm still not quite sure what is causing this, but I'm going to have to assume that CubeCart is at fault because its just too weird otherwise.

Thumbnails keep disappearing, as in - the file is being deleted. I'm not yet quite sure why or when, but i'm guessing that it happens when I edit the product (since I know CubeCart tries to regenerate the thumbnails).

I currently have GD enabled (version 2). I'm running CubeCart 3.0.6

Two other users, smallbang and suss, have both reported the exact same problem. (Another thread here)

To be honest it looks like a new bug in CubeCart 3.0.6

Sir Will, are you going to save us this time?

Estelle.

Come to think of it, perhaps its an incompatability with a newer version of PHP? I know my webhost provider did something to PHP recently (i'm assuming they upgraded it), because I initially got some GD library error messages, but they've since gone away.

This is the only interesting stuff i can see in Server Info:

PHP Version 4.3.11

GD Version bundled (2.0.28 compatible)

[Guest nightmare]

got answer from my webhost... they say they change back to old php 4... and ask me to see if it helps...

not very much of help thou I suppose

Actually, this happened to me twice before upgrading to 3.0.6 . . . while running 3.0.5

I thought it strange but never mentioned it here.

Just noticed this on mine 2 couple of products had thumbnails deleted using v3.0.5

never saw it before i upload to froogle very strange :errm:

[Guest idara]

Hi

I tried editing my products, Thumbnails working fine.

CC v3.0.6

PHP Version 4.4.0

GD Version bundled (2.0.28 compatible)

My thumbnails are being deleted as well, I'm running 3.0.5 (didn't even attempt .6) and my host just upgraded PHP.

edited to add...

Not sure if this helps, but this is the email sent by my host before the PHP upgrade...

MAINTENANCE ACTION:

----------------------------

Please be advised that with the change from the 4.3.x versions of PHP to the 4.4.x versions, a bug was fixed that affects how references are handled. This may in some rare cases cause warnings to appear in PHP pages where there were none previously. More information on this topic is available at the official PHP web site here.

[Guest estelle]

Okay, it seems to be due to a change to the way the way the imageJPEG() function operates. I'm looking into finding a fix...

[Guest estelle]

Okay, I can't replicate this bug because I think my webhost company must have recently reverted to this version of PHP (4.3.11), but I'm guessing they had previously tried upgraded to PHP 4.4.1 which appears to be the problematic version.

So can someone who can replicate the problem please test the following code change...

Edit classes/gd.inc.php

Find this line:

function save($save="")

Now scroll down 14 lines and find this line:

  if ($config['gdversion']>0) {

Insert these lines *below* it:

  // Estelle - fix for imageJPEG() problems in PHP 4.4.1

  touch($save);

Estelle.

Ask host to patch PHP 4.4.1. In safe mode there is a bug in gd.c

:errm:

[Guest estelle]

Yep, convict is right, but it doesn't matter whether you're running in safe mode or not (most people aren't). There's more info about it here.

[convict]

...it doesn't matter whether you're running in safe mode or not ...

Really?

(PG(safe_mode) && !php_checkuid(fn, "rb+",  

CHECKUID_CHECK_FILE_AND_DIR)))

BTW stable hosting company is ALWAYS providing PHP in safe mode only. They know for what.

@estelle may i guess? You are using PHP in safe mode too...but id doesnt matter who is right and who is not :errm:

[Guest estelle]

I can confirm that I am not running safe_mode now, nor was I running it a few weeks back or anytime earlier than that. But I guess my webhost company must have switched safe_mode on at the same time as they tried to upgrade to 4.4.1....

I'm happy to admit when i'm wrong, but i always harbor a grudge towards the person who pointed it out :errm:

[convict]

women must be always right :errm:

[Guest estelle]

women must be always right

LOL... whatever. I did point out twice that you were right, in this thread alone... :errm:

[convict]

MEAN NO HARM

dont take it big, please estelle :errm:

[Guest jodi]

I was going to test it out that fix tonight, but appearantly my host has fixed the problem...

[Guest sunshine]

Yep, that was one of the issues I had. Can't verify PHP4.4 was the reason, but the day my, 'then' host upgraded to that are when I got new problems.

[Guest designsolutions]

;) it Works!

Thanks Estelle, our images are back!

[Guest Bindi]

estelle, would this fix work on version 2.6 of cubecart - i `have someone who won't upgrade and with php 4.4 i have a issue creating thumbnails.

If so which files get upgraded as ver2 does not have the gd.inc file mentioned

thanks

JMHO!!! for people reading this thread - while Estelle's fix may be a good workaround, note that there is nothing wrong with the CubeCartâ„¢ code here - the problem is a bug in PHP 4.4.1

Rather than patching CubeCartâ„¢ files, I would suggest you contact your webhost, and ask them to apply the patch to 4.4.1 and THIS WILL FIX THE PROBLEM FOR EVERYONE ON THEIR SERVER.

If you have a really good host, you do not have this problem - because they would be aware of this bug, and their PHP version will already be patched.

Just send this link to your webhost, explain the problem you're having with GD on your ecommerce site, and ask them to patch the PHP 4.4.1 files.
