Unreadable pages (http encoding issue?) on 5.2.0j

**iancomtek** · 2009-10-19, 10:30 AM

Sugar's pages on my dev machine are completely unreadable. I suspect this was caused by a software upgrade.

I've attached a screenshot of what I see in Firefox or IE if I visit 'http://sugarcrm.dev/index.php'. Visits to 'http://sugarcrm.dev/install.php' correctly display the 'installer locked page' so the Apache vhost is still generally able to serve pages.

Using Fiddler (debugging proxy) I see the HTTP request/response looks like:

Request:

Code:

GET /index.php?action=Login&module=Users&login_module=Home&login_action=index HTTP/1.1
Accept: */*
Accept-Language: en-gb
UA-CPU: x86

Cookie: PHPSESSID=3ca30c3007fe537c43e2593c018022d4

Response:

Code:

�

If I use the hex view I see complete binary jibberish (the fourth character is a null which, I think is why only 3 characters of the response show above).

Initially I was using some version of 5.2.0. I used 'silentUpgrade.php' (since I couldn't log in) to upgrade to 5.2.0.j with no change.

Can anybody shed some light on this? I'm at my wits end.

Thanks.

Perhaps the same zlib-issue as here: http://www.sugarcrm.com/forums/showthread.php?t=52694 ?

**iancomtek** · 2009-10-19, 07:15 PM

Fixed! :-)

Interestingly setting (in php.ini)

Code:

zlib.output_compression = Off
;zlib.output_compression_level = Off

Fixes the issue except for a tiny bit of corruption at the top and bottom of the page. Applying the suggested patch in the thread fixes the problem entirely.

Thanks,

Ian
