SQL Error during import

I am the one with the problem. When editing the file, I get this.

Trying to delete the line, I get this error when running the restore. The restore fails fairly quickly, right after starting to unzip, and before any text dump

I do the following.

  1. I have renamed the backup to “original-cocos2d-forum-2015-05-01-041307.tar.gz”
  2. I then create a new folder: “mkdir cocos2d-forum-2015-05-01-041307”
  3. I unzip the original backup: “tar -xvzf original-cocos2d-forum-2015-05-01-041307.tar.gz -C cocos2d-forum-2015-05-01-041307”
  4. I switch to the folder, and fire up nano: “nano dump.sql”
  5. I goto the line by using Ctrl+_ and enter line 3864981. I edit the line from: “CREATE UNIQUE INDEX post_timings_unique ON post_timings USING btree (topic_id, post_number, user_id);” to “-- CREATE UNIQUE INDEX post_timings_unique ON post_timings USING btree (topic_id, post_number, user_id);”
  6. I Ctrl+O and Ctrl+X out of nano
  7. I switch back to backups/default folder, and create a tar.gz: “tar -cvzf cocos2d-forum-2015-05-01-041307.tar.gz cocos2d-forum-2015-05-01-041307”

In FileZilla, it then looks like this

I really hope you can help me.

Cheers
