Yes you can. I've seen that error a couple times. If you post a new event, inline mod should work fine.

For others having database errors, follow these instructions.

First thing I would suggest is verify your table prefix in /forum/includes/config.php then run these queries one at a time -
replace [prefix] with yours
(coded so the pirates can't get it. lol)

ALTER TABLE `[prefix]event` ADD `nwt_threadid` INT

ALTER TABLE `[prefix]event` ADD INDEX (`nwt_threadid`)

ALTER TABLE `[prefix]thread` ADD `nwt_eventid` INT

ALTER TABLE `[prefix]thread` ADD INDEX (`nwt_eventid`)
