White screen after successful logging in to admin

[beadedlily]

Version 1.51
PHP Version: 5.5.38 (Zend: 2.5.0)
Website: tubularwiremeshribbon . com

After a nameserver change to facilitate transfer to a new host I'm seeing a white screen after logging in to admin. After successful login I am redirected to a this page, which is blank (white):
https:// tubularwiremeshribbon.com/admin-name/login.php

or to the same url with a session ID, which is also blank (should there be a session ID in the admin?). However, if I then access the admin directly (tubularwiremeshribbon.com/admin-name/) I am indeed logged in and can access my admin, although if I make an update within the admin I am then redirected to a BLANK success page.

I understand that an upgrade is certainly recommended, and it is indeed on my to-do list. However, if possible I'd like to resolve this and delay the upgrade just a tad longer as I complete other tasks.

Any thoughts/comments are very much appreciated.

As always, a blank page or one that does not completely render (partial blank page) likely generates a myDebug type log. This is discussed in the following FAQ: https://www.zen-cart.com/content.php?124-blank-page.

It may also relate to actions very recently taken and unrelated to the "site move" if the site is still in the same location it was before the most recent change(s) such as reported as being performed/completed just 10 minutes before posting this issue at: https://www.zen-cart.com/showthread....e-to-new-host) where it would seem that operation was normal with exception of updating currencies.

Thanks for your note. In the currency thread I was speaking of that specific issue being resolved. This issue with
the admin began prior to that.

I'll take a look at blank-page thread you recommended...
