What version PHP you got?. version vb4 is made for PHP 5.4

Following the install script, it seems you already run the upgrade.php script multiple times. The step 1 is creating the cms_grid table and fill the data correctly but on step 8, it renames the column 'columns' by 'gridcolumns', which makes this error if it's rerun. You should try to rename 'gridcolumns' column by 'columns' and retry to do the upgrade.
