CB Conditional has not been upgraded for CB 2.0 yet. I'm currently working on upgrading CB Privacy. CB Conditional upgrade will be next. That issue is due to how parameters are now saved as json and maintain arrays. The function that's erroring is probably trying to explode an array. The below might quickfix this.
IN: components/com_comprofiler/plugin/user/plug_cbconditional/cbconditional.class.php
ON: line 371
FROM:
Code:
$param = explode( '|*|', $param );
TO:
Code:
$param = ( ! is_array( $param ) ? explode( '|*|', $param ) : $param );
I won't know the extent of the issue until I've started the CB Conditional upgrade.
