OK. i will reply to my self :-) But for others, the problem is in administrator/components/com_joomdoc/libraries/joomdoc/filesystem/filesystem.php, where is condition (around line 462):

If the 'mime_content_type' function doesn't exists, there is not Content-Type header added to document, simply adding one else with fallback to 'octet-stream' solves this (for me):


There exist the fileinfo functions in PHP too, but at my hosting they do not works...

Thanks to artio for great component (realy) and for great support (joke)...

Finally, here is more Joomla's solution:

it does exactly the same as previous one, only it is simple to understand

when trying to download some document, it can be downloaded, but the content-type is "text/html" and not by the real file type. by this, the browser is confised, when it gives the "open with" option.

I tried disable/enable SEF, without success.

Is here some configuration for it? I can fint nothing related...

Joomla 1.7.0 an JoomDoc 3.1.2

in administrator/components/com_joomdoc/elements/icons.php file add before line16:

require_once(JPATH_SITE . DS . 'libraries' . DS . 'joomla' . DS . 'html' . DS . 'parameter' . DS . 'element.php');

to remove error message and allow config dialog to be accessible.

Yes, the same error, the same versions of Joomla and JoomDoc...

But i am not new to joomla, while i remmeber and was using original DocMan a lot of time ago :-)
