See the chars in your pic above in the ' ' search for that word in the sql file, then the 2nd occurance then remove everything before that line & remove that line & continue the import with the file.
Make sure you still have the orignal full file before editing the data out.
Ch3tosYou just need to check in the backup file for INSERT INTO `xf_tag.tag`
Check if there are multiple lines with your text which is shown in the picture above, if there are multiple lines for that compare them and decide which one to delete.
