Can't use drop down menus to configure shop

[ZORANVEDEK]

...see attached image. I can't access them  at all.  Running on a windows machine in a local environment in XAMPP.

Okay,  went to  reinstall everything to  try and fix this,  got a  notification there was a an update so  this is in version 1.7.6.9,  and it's still  doing it. 

If anyone can  give me a clue as to  what  might be going on, it would be immensely appreciated.  As it stands right now,  Prestashop is completely useless for me.  I quite literally cannot change any settings that rely on a drop  down menu(they are ALL unusable).  In other words I can't change much  at all,  and I have no idea how to  go  foraward from  here...

Okay,  I figured this out,  had to  roll  back  the PHP to  version 7.3.23...

... it's working now. 

I'll leave this right here in case someone else needs it--might save them  form  banging their head against  wall  for a few hours like I was.

Even 7.3. is too high and you might face further issues. Prestashop 1.7.6 is officially only compatible up to PHP 7,.2

Thanks for the heads up  and I will  keep  that in mind,  might even  go  ahead and roll it back  further. It's working now,  but I don't want to  run into any  more problems if they  can be avoided.
