This error occurs on four separate lines. Below is the code as it is written in BxBaseConfig.php
plugi2n_insertdate_dateFormat : "%Y-%m-%d",
plugi2n_insertdate_timeFormat : "%H:%M:%S",
Below, is how it should read:
plugin_insertdate_dateFormat : "%Y-%m-%d",
plugin_insertdate_timeFormat : "%H:%M:%S",
This affects the insert date/time functions in the TinyMCE editor, and unless corrected, will not allow changing the format of the date.time that is inserted in the editor.
Edit: I'd add a ticket to track for this, but since there is no 7.0.6 milestone, and 7.0.x is a repository for things Boonex doesn't consider important, and 7.1 is probably a year away, I am at a loss as to where to add a ticket.
