[Mark Wu]

Today when I go to back office, i found the "module" tab is not able to access, when I choose it, no module shows, please see attachment pictures, anyone could help?

Other tab no problem, orders, customers are normal, only "module" and "payment" not able to show.

Have you added a new payment module recently, because it looks like that is causing the problem.

No, I did not install any modules recently, what should I do now? delete all the payment modules?

Is it just a default installation?

Edit config/config.inc.php and temporarily change 'display_errors' from 'off' to 'on'. That will give us an error message instead of a blank page.

Since no error message is displayed, you can't pinpoint the cause of the problem. Your only option is to delete modules off your server one-by-one starting with the most-recently uploaded until the Modules tab works again. Once it does, you know that the last deleted module is causing the problem.

Thanks, I will try that and let you know result.

I have another questions, I have another website, the homepage I can not open, but I can open back office.
When I disable the shop, the homepage is able to open, and hows the shop is Maintenance.
When I put my IP into Maintenance IP, the homepage is able to open.
When I enable the shop, the homepage is not able to open,
Why??

I have no idea. I've never encountered that problem before. Try editing config/config.inc.php and temporarily changing 'display_errors' from 'off' to 'on'. That will let me know whether there is a PHP error.
