I just installed latest version of piwigo. Feed are not working because of syntax error in XML;
I'm not sure exactly what firefox don't like.
maybe this :
<!== *** PiwigoPress Getmode = *** ==> <!== *** PiwigoPress Getmode = *** ==>
or maybe something else like :
</div></div><!-- PiwigoPress Ended --></p> ]]></c
thanks a lot for help,
