IIS RTE not loading in 2.1

[sunburntkamel]

tinyMCE is not loading in both my installations of 2.1.

ENV: IIS, with MySQL 4.1.21-community-nt
PHP Version 4.3.1 CGI/FastCGI

2.1alpha3: ​http://archgfx.net/sandbox

2.1beta2: ​http://archgfx.net/wordpress

PHPinfo: ​http://archgfx.net/phptest/phpinfo.php

FWIW, my client is windows XP SP2, and it occurs in both FF 2 and IE 7

firebug shows the following errors:
invalid flag after regular expression

tinyMCE is not defined

Are you running a theme that includes a copy of prototype?

newp, neither installation.

looking at:
​http://archgfx.net/wordpress/wp-includes/js/tinymce/tiny_mce_gzip.php?ver=20061113

i see the last line refers to ob_gzhandler, which doesn't work/exist on my server. is there some setting that should be flipped to turn it off?

You have the zlib extension installed, so ob_gzhandler() should exist. The error suggests that ob_gzhandler() is being run twice. If you have plugins activated, check to make sure none of them invoke ob_gzhandler(). Failing that, if you can edit your php.ini, try setting output_buffering to Off. It is currently 4096. I don't think that should matter since zlib.output_compression is off, but it won't hurt to check.

alright, last time i had trouble with ob_gzhandler() loading twice, i deleted it from functions.php, and that fixed it. i can't edit php.ini myself, but i've asked my host, and i'll let you know.

and no, no plugins. except akismet.

i added:

ini_set('output_buffering', 'off');

to /sandbox/wp-config.php, still nothing.

fwiw, both installs are running 2.1.0, and they still don't work.

if having admin access would be helpful, drop me an email:

Does deleting ob_gzhandler() fix it?

i deleted it out of

/wp-includes/functions.php

​like this, but no, it didn't help. is there someplace else i should delete it?

check wp-includes/js/tiny_mce_gzip.php

I missed a directory there but I think you can find it :)

modified tiny_mce_gzip

alright, i deleted everything from line 132 to 137, now it works.

I was having the exact same problem. I commented out the entire Check for gzip header or northon internet securities section from 131 - 145.

That led to out of memory error to which I added:

ini_set("memory_limit","12M");

after the first require. It now works. I'm not sure I fixed anything but if memory serves me correctly from my old C programming days leaking memory is never good but if you are going to leak assign a big buffer to your array... ;) That way your problem will happen much later and may never crop up if the process gets terminated/reset before you run out of memory.

Reporters problem seems fixed by the "hack".

Is there a way to test for this issue and include a permanent fix in core or is this so rare that we'll just learn to live with it?

the hack is no longer working.

updated patch for 2.1.1

trunk has a new tinyMCE compressor that might help.

yep, latest SVN works on a test install.

Excellent, we will call this fixed then.
