Hi everyone.
I am trying to upload images, but after uploading the image automatically appears broken, when I download the file size remains the same amount of bytes but can not open in an image viewer.
I checked the permissions 4 moodle data and moodle application's folder, and its everything okay.
I'm trying to re-upload all the images used by my theme, such as the logo, because they are all broken.
Could someone tell me a way to debug this problem or sometimes a possible solution?
Thanks!!
* switch on Debugging
* right click on a broken image and open in a new tab/window
* what error messages (if any) do you see in the new tab/window?
Icon's images show this error (in new tab)
"error on line 2 at column 6: XML declaration allowed only at the start of the document"
I dont know why, but when i click to see de page's source code, in the first line i found a blank line...
1.
2. <!DOCTYPE html>
3. <html dir="ltr" lang="en-us" xml:lang="en-us">
I run this command
diff -y <(xxd downloadedimage.png) <(xxd originalimage.png) | colordiff
00000000: 0a89 504e 470d 0a1a 0a00 0000 0d49 4844 ..PNG..... | 00000000: 8950 4e47 0d0a 1a0a 0000 000d 4948 4452 .PNG......
So... i don't know why but when i upload an image, moodle add's/changes the first byte as we see above...
Just as POC i made this simple script, where i download a "corrupted" image and save them without the first byte, so... this works \o/
<?php
$binary = file_get_contents('downloaded.png',0,null,1); // 1=offset
file_put_contents('./newImage.png', $binary);
?>
Check your config.php file. Has an extra character crept in before the initial <?
...or, have you added a final ?> (don't)
Hello,
I second Howard's suggestion: 0A means Line Feed.
Please double check your config.php file and any third party plug-in you've recently installed: there, you should find the extra LF.
HTH,
