Binary Ver: 4.8.3-2634408

After upgrading Unreal Engine from 4.8 to 4.8.3 (directly, I didn’t update for a while), all the UI I’ve made with widget blueprints are now not working.

For example, in the project (RTS game) there is a system to select a single unit by clicking on it. Now I can click on it through buttons, for example.

In the example gif you could see me selecting a unit through a button. Normally (4.8), the button should be pressed rather than the selection of the unit.

Repo:

Create a widget with a button. When the button is pressed, try to print “Hello World”

System:
Win7 Home Premium, Intel i5 3470, GTX 670 by Gigabyte

Due to the fact that no crashed occurred, no crash log was created.

Note: All widgets are enabled. Please help! I can’t make a game with no functional UI!

@birdfreeyahoo Yes. They all did. I’ll try to make a new project and test it out.

You had the button before?
My buttons are still working fine.

I also created a new button and it worked.

I’ve created a new project, and there it is all fine and good, yet in the one I’m working on the UI is messed up.

Fixed it by making a new project with the same name, and then using files of the old project via source tree.
