Customize Single Posts setting

Hello,

I’ve added more posts and tried to customize in Single Posts. But nothing happen.

I also tried to import your demo data. But it didn’t work too. It shows the error as below

Thank you,

Fatal error: Maximum execution time of 30 seconds exceeded in C:\xampp\htdocs\wordpress\wp-includes\wp-db.php on line 1877

Yes, I am trying in localhost.

How to say…
My situation here: i have two laptops, they have the same problem. I cannot customize the single posts.

For the import data: I think it is not related ” Maximum execution of 30 seconds exceeded” Because , the first laptop just shows the import error as above. The second laptop, it too slow that why this is happen.

Could you support me via TeamViewer or Skype? What is convenient time for you. I will be ok from 8p.m to 12 p.m, My time zone +6.

Thank you

The import data works now ..
I have set_time_limit(300);

But Single Posts customizer still not working .. What did i need to do now?

Thank you,
