Admin page goes blank

[pureclothings]

I was trying to create wholesale section in my website. I made a copy of retail website and did the necessary changes. Then I uploaded it inside wholesale folder. I can access all the pages in wholesale section but can;t access the admin panel. When I open admin panel, the page goes blank. So, can you please tell me what can be the problem and help me to solve problem.

 

Link of wholesale admin panel is pureclothings.com/wholesale/aadmin/

I guess you made some customization changes and some code caused an error.

Or you installed some 2rd party module caused the error. It is difficult to tell from which file from the messages.
