Incomplete loading of back end pages.

[Adepeju]

For a couple of days now, my back end pages have not been loading completely. Sections like products options don't load at all. At first I thought it was the network but realised it wasnt.

I have not been able to change attributes, variations, shipping etc as a result.

This also affected many other pages like home, customization, product reviews.

Pls see attachment.

Kindly assistant, I need this done ASAP.
