When I try to update my roster with my character profile and raidtracker, I get this message.

Database Error
1265: Data truncated for column 'end' at row 1
SQL:
INSERT INTO `roster_raids` SET `raidid` = '2007-07-27 18:32:26', `instanceid` = '895358', `zone` = 'Karazhan', `end` = '2007-07-28 0:16:28', `note` = ''
File: trigger_functions.php
Line: 91

Any suggestions or ideas?

Fixed the problem by setting MySQL to not run in Strict Mode.

Yes, but it will still truncate the data, it just won't give you the error anymore
That field in the database need to be longer

The end field probably is a varchar field,
If so change it to varchar(20)
If it's a datetime field, it shouldn't be having this error

end is an INT(12)

Oh yeah, good point on the truncating of data. I checked and it only had "2007" instead of the whole date and time. I changed that column to also be a datetime field and manually entered the date and time.
Don't know if this affects anything, everything imported correctly and looks correct.
I'll try the default MySQL settings next time I upload and see if that solves the problem.

Yes, change it to a datetime field
That would be the best bet
