The upgrade worked okay on my system. Based on the error that you posted here it literally says its lookig for a column (ft) in the ost_file table and it doesn't exist. This gets added by the upgrader in: \upload\include\upgrader\streams\core\852ca89e-740428f9.patch.sqlHere is the SQL for it:ALTER TABLE `%TABLE_PREFIX%file` ADD `ft` CHAR( 1 ) NOT NULL DEFAULT 'T' AFTER `id`, ADD INDEX ( `ft` );
I'm not sure why it didnt add it... so it fails trying to add the new columns for 1.8.1. It should have been added in 1.7.1. Are you sure that you were running 1.8.0.2? Or did you modify the table yourself?As a side note the SQL that its crashing on is located in:\upload\include\upgrader\streams\core\934954de-f1ccd3bb.patch.sqlWhich you may need to run manually afterwards.
