Hi Paulo,

seem your issue same like:
www.jomsocial.com/forum/installation/20879-nginx-compatibility
this is the issue with joomla Nginx site config

please put the following rewrite code at the Nginx site config for your site.

if ($uri !~* administrator) {
rewrite /\w*/index\.php http://your site domain/index.php$1 redirect;
}

I had already tried that, doesn't works because the browser send file and payload to one url then they receive an 302 to move to other url and the file is not uploaded to the new url.
The error is a json with an message like "file format invalid". So no one upload image in message field works, including one that was working, stops works, no working anymore.

{"error":"Tipo de arquivo enviado n\u00e3o \u00e9 compat\u00edvel."}

this means something like "file format invalid" or "incompatible file sent".

This is the same as access url directly without send any file.

Hi Paulo,

this issue only happen on NginX, seem joomla site config not properly works.
give me time for this. I must setup my local test site on NginX enviroment.

Regards,
Albert

Hi Paulo,

here the fix:
1. edit /components/com_community/assets/_release/js/bundle.js
2. find (using editor tool) any ajaxPreviewComment. you will find 2 location with this

index.php?option=com_community&view=photos&task=ajaxPreviewComment

/index.php?option=com_community&view=photos&task=ajaxPreviewComment

Hi Albertus,
The image is sent perfectly now. :)
Thank you!
