SD warehouse, Extensions warehouse etc showing blank screen

Been having issues today with sketchup on loading will only show a blank screen. now i have managed to fix that with the help of others but when i go to click on the extensions i just get the same blank screen. theres no search bar etc. It is weird as Sketchup was working perfectly fine a few days ago.
I have updated all drivers for graphics card, made sure its running on the nvidia 1050 and not the integrated graphics card.

Are you working through a browser or with downloaded software?

Presuming SD = 3D, and if you can’t get to those, can you get to or in a browser? If you can, then it’s probably some bad web cached state in the embedded browser. Search the forums for “clear webcache directory on Windows” for instructions.
