Hi Rainer,
It seems I'm having the same problem. I just installed the iosc add-on and only my HOME and ACCOUNT pages are working. The STORE, SEARCH & INFO links all return 'Error Loading Page' messages.
Can you explain exactly how I need to add the mods in the tep_href_link funtion please?
<?php
function tep_mobile_link($page = '', $parameters = '', $connection = 'NONSSL', $add_session_id = true, $search_engine_safe = false) {
return tep_href_link($page, $parameters, $connection, $add_session_id,false);
}
