Sorry to hear of the problem you are having.
The error occurs when server allocates less than required maximum execution time to PHP so try increasing maximum execution time by using following solutions and if the solutions don’t help then contact your web host to increase it.
Thanks For Reply, But Error Not Fix :
; Maximum execution time of each script, in seconds
; Note: This directive is hardcoded to 0 for the CLI SAPI
max_execution_time = 9000
and not fix, please send file of demo content.
You can download demo content from this page http://remote.demos.shufflehound.com/gillion/files/?key1=nb3javfj03&key2=40legtcdrh
After downloading demo zip file you have to add it on the path wp-content/uploads/fw-backup in your WordPress install.
Then that zip file can be installed from Tools > Backup by restoring backup.
Please note installing demo content is not revertible and it deletes all the existing content on your site so please it is advised to take backup of your site before importing demo content.
