I cannot get into the content area of AbanteCart back office.  The error message is:
2013-08-09 16:09:37 - load error:  AbanteCart core v.1.1.6 Error: Could not create grid. Grid column model contains reserved column name ("parent"). in <b>/hsphere/local/home/a892501/colecon.biz/AbanteCart/abantecart_v1.1.4/public_html/admin/controller/common/listing_grid.php</b> on line <b>101</b>

I have no idea what this means.  I updated to 1..1.6 today.  I could get into Content before the upgrade.  Please help me...

Thank you
