Restore error

Im new here, im using 1.5.5.1 version of opencart ....after backup my file....when i want to restore back the previous one....it show this kind of syntax error...and i don't know what is the problem...anyone here can help me?

Please reply me at the below.

This is what i found in line 50


trigger_error('Error: ' . mysql_error($this->link) . '<br />Error No: ' . mysql_errno($this->link) . '<br />' . $sql);

In your system/logs folder, could you post the line in details here ? Only then would be possible knowing the cause of this problem.

@straightlight

First of all thanks for you reply and support.
Here is the code but there are some other errors too.
Could you look for it if you feel free to check it out.

This error can be seen either if, when true, that MySQL server has been disabled from your domain but might not be accurately be the case at all times or it can also happen when too many queries are being executed during the default tolerable length of 30 seconds delay from your web server which your database size seem to require a longer time period to restore. I would rather suggest to try to restore your database with PHPMyAdmin then from OpenCart's administrative console. PHPMyAdmin is installed by your web host as the length of time before the expiration can be reached is way more extended as it also avoids data corruption.

If restoring your data from PHPMyAdmin does not solve the issue, I would then suggest to contact your host knowing why this message would appear.

Thanks for the information~ Because i'm new with this kind of thing~ doing my final project~ a little bit blur with this kind of code and unsure what is it~ Actually some other reason is sometimes my line is not good and i know it...i will try to backup at my server if there is no error then thanks God =)
