I'll publish a update as soon as possible, for now:
@joransrb
mod_exdata/install/config_v2_new.php
line 93:
`cat_field_number` TINYINT(4) NOT NULL default '',
change to:
`cat_field_number` TINYINT(4) NOT NULL default '0',
sorry, it's a stupid error!
@DF6IH
in the main.functions.php delete all functions exept:
showCategories($value)
the other ones are NOT used in ExData but still there since copied from Ionrods CalendarMod

There are problems in frontend with paging- and order-function, update is on its way...
@ludwigvb
I didn't think on the fu*** db-prefix
mod_exdata/inc_lib/exdata.classes.frontend.php
line 161:
function make_auto_image($value) {
$sql_file = "SELECT * FROM phpwcms_file WHERE f_id=".$value[1].""; //select entry in db
change to:
function make_auto_image($value) {
$sql_file = "SELECT * FROM ".DB_PREPEND."phpwcms_file WHERE f_id=".$value[1].""; //select entry in db
mod_exdata/inc_lib/exdata.classes.php
line 127:
function make_auto_image($value) {
$sql_file = "SELECT * FROM phpwcms_file WHERE f_id=".$value[1].""; //select entry in db
change to:
function make_auto_image($value) {
$sql_file = "SELECT * FROM ".DB_PREPEND."phpwcms_file WHERE f_id=".$value[1].""; //select entry in db
this should help for the moment, sorry guys!
