Unable to upload images on new 2.3.0.2

I have issues uploading or choosing images to add to my site since updating my site to the latest version 2.3.0.2.

If I add a new product or category and attempt to add an image, the window opens and I can select from the first page of images only, but it wont allow me to upload it. I can not upload images from my computer either. Also image pages from 2-6, is just a mess - see attachment screenshot.

This is leaving a few of my categories and products with an opencart logo.

Help please!

Which version did you update from?

1.5.6.1
It turned out to be "cloudflare blocking the port on the callback" - whatever that means...

uploading was fine by me, but the search function in the image manager dont work form me.
Do you have the same?
When uploading an image and searching on the name and click search glass icon.

sombody have a fix for this?
