Bumped again.

Added more info and suggested fix to the ticket. Very similar to other issues reported and fixed in Wordpress and Drupal a year ago. Still not sorted in trunk.

Really hope that someone makes this change soon. Silverstripe.com looks *really bad* through our squid proxy. No css, broken links, random characters at the top of the page.

Bumping this thread again because I'm not sure that the SS guys realise that this is borking their own website. I've attached a screenshot of what silverstripe.com looks like for me on the open ticket here:

http://open.silverstripe.com/ticket/2529

At two different companies through two different firewalls, the silverstripe website is broken. It is also effecting my site and several sites I've looked at through the showcase.

Note that when I'm not behind a firewall, it looks fine.

Back Again! Just wanted to mention that this bug occurs on the silverstripes demo. If I click on flickr or gallery module I get:

XML Parsing Error: syntax error
Location: http://demo.silverstripe.com/flickr/
Line Number 1, Column 1:
3ff6

Oh one thing - that fix does not work for 404 errors. Instead it adds those random characters back in and breaks the page. I have just commented the entire line out for now so that everything works.

YES! Finally I have been looking for a fix to this bug for ages. Was causing me major stress. I was convinced it was to do with my apache configuration. I tried two different installations using WAMP and XAMPP but to no effect. I also noticed the issue occurs depending on the length of your HTML code. If I was to remove a few Includes then the whole site would start working again. As soon as it goes over a certain length it would switch the transfer encoding to chunked and those random characters would appear at the top and bottom of the html code and break the entire structure. Thanks for the fix it is much appreciated!

The bug is caused by one of the headers sent in the output() method of HTTPResponse.php. If you call echo " ", then it's preventing headers from being sent and therefore fixing your output.

I suspect that it is this line is the culprit:

header("HTTP/1.1 $this->statusCode " . self::$status_codes[$this->statusCode]);

You might want to try changing it to this and seeing if that fixes it instead of the "echo" fix that you made.

if($this->statusCode != 200) header("HTTP/1.1 $this->statusCode " . self::$status_codes[$this->statusCode]);

Heh, that last post was from me - I was logged in as Mike! Sorry about the identity theft, Mike. ;-)

This looks suspiciously like the chunk-size characters that HTTP chunked transfers add to the stream.

For this reason, I suspect that this is happening because of a quirk in your web server configuration. Could you tell us a bit more about the web server that you're running on?

* Apache, or something else? What version? Any non-standard modules running?
* What version of PHP?
* What operating system?

If you could email me some details (to sam at silverstripe dot com) of where your server is running so that I could access the site myself, I could take a look at the raw HTTP output to see if I can determine what's wrong.

i removed all of my code and even did a fresh install - didn't solve the problem.
i expected this, as my workaround (see previous posts) deals with untouched core files, although project code may suffer from the same problem in case a method returns something integrated in the final html output (as mentioned before)...

This is some odd behaviour indeed, something that I've noticed before on another SS installation as a similar problem (a strange character left above the <?php tag on a class), but haven't personally come across it myself.

Have you tried removing all your custom project code, to leave a bare SS installation? This could help pinpoint exactly where the problem is occurring.

Typically this is a good way of debugging if you've got a problem like this, as it's not actually giving any errors! (d'oh!).

finally, the characters even arrived in the frontend site itself.
this allows me specify the problem a little better:
the characters seem to appear whenever a string is returned by some method and integrated in the html output. in addition, the string must have reached a critical length (i can't determine the exact limit).
whenever you 'echo' some string before the return statement, the characters are gone.
i was wondering wheter this has to do something with output buffering.

after several hours on irc (many thanks to all folks there) on many more hours alone on my own, i finally found a fix for this (ss version 2.2.1).
in fact i don't know what exactly causes this error, maybe a bug in php version 5.2.5?
to fix it do the following:

file: sapphire/core/Requirements.php
line: 183
todo: before â€˜returnâ€™ statement, add a line with â€˜echo â€ â€œâ€˜
â€“ and â€“
file: cms/code/LeftAndMain.php
line: 205
todo: before â€˜returnâ€™ statement, add a line with â€˜echo â€ â€œâ€˜

this is just a workaround, any further description/fix for this problem is appreciated.

weird characters in cms

schellmax — Sun, 18 May 2008 01:28:11 +1200

hello,
after installing silverstripe on a client's server, weird characters are showing up in the cms.
unfortunately uploading attachments in this forum seems to be buggy - i can't.
the characters appear just before any html-code (even before doctype declaration), they change every time i log in, always 4 characters like 'ad28'.
the frontend site itself is clean.
has anybody an idea where this may come from or maybe a starting point where to search for a possible problem?
thanks in advance
