Manager goes blank when compressing js and css

If I turn on compression for css and js in system settings the Manager goes blank except for the top menu.

I can get it back by changing the settings back again via the DB admin and deleting the cache thru a control panel.

However, I'd still like to be able to compress the css and js.

Does anybody know what's causing this and how to fix it or get around it?

Thanks

Hello,
While I am hardly a system guy I am going to go out on a limb and take a guess. I (think) it has something to do with your suhosin setting(s). I have seen this error come up before when I have installed MODx on one of our servers:

Currently, you are using the PHP suhosin extension, and your suhosin.get.max_value_length is set too low for MODX to properly compress JS files in the manager. MODX recommends upping that value to 4096; until then, MODX will automatically set your JS compression (compress_js setting) to 0 to prevent errors.

That's about all the more help I can be. If you somehow increase that limit I think you will be in good shape.

Jentree,

yeh from what I can tell from the php.ini it's already set to 4096, though I could be wrong.

Not entirely sure how to change it.

Yeah... that's where I am literally no help at all. I submitted a ticket to our hosting provider to up the limit and it just "magically happened".

Hi Mark, had the same exact problem - still having it. Well at the moment I can live with the turned off compression - but I'd like to have it turned on. In the meantime I changed the following values in config.cache.php in core/cache/system_settings:

I manually changed 1 to 0

 'compress_css' => '0',
  'compress_js' => '0',

than in the manager I went to the settings panel and turned js and css compression off again - so it won't change back - even when the cache is deleted and reloaded.
It's not a fix for the problem, but than you don't have to do it through db all the time.

If you find a real solution for it, I am very interested.

I found this in the modx rftm about the prob with suhosin:

I've found it much more reliable to enable compression via htaccess, plus you get the added benefit of static file compression in the front-end.

# compress text, html, php, javascript, css, xml:
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE application/x-httpd-php
AddOutputFilterByType DEFLATE application/x-httpd-fastphp
AddOutputFilterByType DEFLATE image/svg+xml

# Drop problematic browsers
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html

# Make sure proxies don't deliver the wrong content
Header append Vary User-Agent env=!dont-vary

Hi Dan!
Thanks, I put your code in my htaccess - but how can I check, if it's working?

Another question to markG - when you turn off all the compression, is a richText editor like TinyMCE still workgin? Because on my setup I don't get it to work...

thanks,

@ad2003,

Re:

1
'compress_css' => '0',
'compress_js' => '0',

that's pretty much what I've already done. The issue is not turning it off, but turning it on in a way that the Manager still works.

Yes it still works.

@Dan, will give your suggestion a go.
