Cannot show image, headers have already been sent #94

srikanttowakel · 2013-06-02T11:00:29Z

All the images that are being resized using adaptiveResize are not displaying anymore.
Site: www.pr-property.com

Error getting from Chrome:
Fatal error: Uncaught exception 'RuntimeException' with message 'Cannot show image, headers have already been sent' in /home/prprop1m/public_html/phpthumb/GdThumb.inc.php:569 Stack trace: #0 /home/prprop1m/public_html/en/cropSquare100.php(48): GdThumb->show() #1 {main} thrown in /home/prprop1m/public_html/phpthumb/GdThumb.inc.php on line 569

They used to display.
Kindly tell me what you need to troubleshoot.

Thanks,
Srikant

Locallly, I am using WAMP and it is OK. When uploading to server, then they do not display.

Hi srikanttowakel. You solved this problem?
I have the same problem in my website, but no found solutions
help me, please.

Hi,

try this: delete the ?> sign from your php file (at the end).
I think you have an empty line at the end of your php script.

Upd.: please check all of the included files in the session.

If this doesn't help, then please compare the settings on your local machine, and on the server.

Hi cbabos. Thanks for reply.
Unfortunately, not work for me :(

cbabos · 2013-09-17T13:23:51Z

Is there any difference in the local config and the server config?

julioaze · 2013-09-17T13:29:38Z

Locally it works perfect. I do not have access to the server settings.

cbabos · 2013-09-17T13:30:30Z

But you can see the PHP settings with phpinfo(); :)

Is your phpThumb cache directory writeable on the server?

julioaze · 2013-09-17T13:34:42Z

Yes! The directory CHMOD is 755

julioaze · 2013-09-17T13:41:05Z

On the server was working normally, then the images disappeared

cbabos · 2013-09-17T19:05:23Z

In this case, there must be a change in the configuration of the server (i think).
I have no exact idea what is it, so it's up to you to experiment with it. Sorry. :(

srikanttowakel · 2013-09-17T19:37:51Z

Hi,
Yes solved the problem partially.
First thing i did was to rebuild the server. But the issue appeared again.
Then i noticed that there was a "error.log" thing file on the directory. I
had to delete all these files, mainly in the phpthump directory and the
images appeared again.

Hope this helps.

I think, that the phpthumb cache directory has another user:group owner than the user:group owner of the apache process.
Maybe that is the change. If this is the situation, then the 755 rights isn't enough because the cache directory isn't writeable by the server. If the images disappear again try the full 777 rights. If this helps, then make sure, that the cache dir is created by the apache itself.

If this is the case, then it's not a problem with the phpThumb code, it's simply a server config issue.
Hope this helps

Hello and thanks again for the answers.
Srikant, I did just that. Deleted the error.log from the server, the images appeared, but then disappeared again.
Cbabos, the folders have permission 777, but not solved too.

cbabos · 2013-09-17T20:07:35Z

Try to enable the debug mode (fully enable, so log messages are shown), and look at the content of error.log
There must be some clue, or hint what the problem is.

it can be also because of memory of the virtual server hosting the website.

scan your "thumb" directory for all "error_log" files or "_notes" directories, and delete them. In my case I had an error_log file at the thumb_plugins, as soon as I deleted it it worked on the remote side.

I came to this because there was no reason why it whould work differently localy and remotely, the only difference was these files.

Good Luck

Hi, I have similar problem. I used PHPThumb on other serwer (it worked properly then and on localhost). Now I am trying to migrate whole portal to another hosting (vps on digitalocean). I've installed Ubuntu (php version 5.5.9-1ubuntu4.9), I installed gd php library too. When I execute a php script that should display image, this empty square is being shown (as on attached screenshoot):

HillbillyGeek · 2018-05-11T20:15:30Z

I also have this: It does sound like a config issue. on a new install locally, the thumbnailer will work for a while and then quit.
I drop a new copy of the core files in and replace the old ones and the problem goes away.
(GdThumb.inc.php
PhpThumb.inc.php
thumb_plugins {
gd_reflection.inc.php
gd_watermark.inc.php }
ThumbBase.inc.php
ThumbLib.inc.php)
