Hi again...
I'm still working on it, because I disable everything and it's not working fast yet. The hosting people says that everything works ok (but they look again... it's a shared host so I can not have enought logs). Joomla log says nothing important.
But one question about groupjive...
It's usual that all code references use full url, not relative?
like this:
'
www.cevilassardemar.cat/webjoomla/components/com_comprofiler/plugin/user/plug_cbgroupjive/plugins/cbgroupjiveevents/js/jquery-timepicker.min.js'
these spend more time than a relative one?
'components/com_comprofiler/plugin/user/plug_cbgroupjive/plugins/cbgroupjiveevents/js/jquery-timepicker.min.js'
thanks, and sorry, but must test everything....
