I've read the previous messages posted in this forum and modified ISPConfig value to 'addtype' (to avoid filters) but without success, restarted apache, etc.

Some readers said that this error is ininfluent, but for my particular case this is very tedious. Infact when I attempt to upload some data through a form (text area) if the content is too large the server answers (it is not possible to display the page) and the upload stops without success.

Thank you

Change the line:

$go_info["server"]["apache2_php"] = 'both';

to:

$go_info["server"]["apache2_php"] = 'addtype';

in the file /home/admispconfig/ispconfig/lib/config.inc.php

This is the correct and only solution!

This is not related to the above error. Just set the memory limit and limit for max. post data size in your php,ini to a higher value.

Thank you for you comment. I discovered the cause of the problem and talk with my colleagues.

Infact it happens that, if you attempt to upload through a form the following line (? is this a Ie/Mozilla bug?!?):

//page.headerData.1.value = <sc ript>alert(document.compatMode);</script>


(note: I've put a 'space char' between 'sc' and 'ript' to ensule this upload...

in the middle of a long text, explorer (or the server?) stops the upload immediately before the line and doesn't upoload the remaining text.

If you are using explorer you will redirected toward a page with "Documents contain no data" and under Mozilla you will receive an alert such as "No data.".

The behaviour changes between different servers, so that I think could be depending from the configuration...


This is very strange... thank you, have luck!!!!!

Dear Sir
 

Dear sir

Replace that line not work for me.

I replace that line and restart apache2 and the same error in error log.

One script in the server report that problem specifically is a script that use gmail for send emails via Pear, that script is not linked from any web page or script be cause i use for test that specific error and resolve that, i think only me access that page, but from any way someone else know the page...

How someone knows that web address?

Why servers with this problem start to be under attack?

ISPconfig is a trouble for me, I Install that and Headache come...

There's no known vulnerability in ISPConfig.

After you've changed your config.inc.php, you must update one of your web sites in ISPConfig so that ISPConfig creates new configuration files. Then the an unknown filter was not added: PHP lines will disappear.

That's a problem of your web application, it's not caused by ISPConfig.

still dont understand
 

I am seein the same errors in my error logs and am not clear how to remove them, i have not changed config.inc.php,

a read in a few places the httpd.conf needs to be edited but in the new version of apache this file is obsolete and empty??

can you help get rid of this error

thanks

You must change the config.inc.php file as described above to solve this. Then modify one of your websites so that the configuration is rewritten.

Thanks till --- Worked like a charm.

Erk..when I do this I get the PHP file printed out in my browser. Debian 3.1.

Any ideas? This is freaking me out...

I'm also experiencing the same problem, I get a number of these every few minutes showing up in the Apache2 log.

I seached for the "$go_info["server"]["apache2_php"] = 'both';" in the "config.inc.php" file but it is not there.

I'm running ISPCONFIG 2.2.9
