Changes made to the theme are not saved

I use a Windows 10 PC and can’t save changes I make to both the public and project themes.
I go into advance mode, make the changes, save, and then go back to check. All the theme settings are back to their defaults. It basically doesn’t save anything. I’ve also disabled Malwarebytes and Adblock (which I don’t think have much to do with it…).
Do you have any idea what could be wrong? It’s working normally for everyone.
Thanks

Hello, i have same problem. I can not change themes.

Hi , so I’m not alone !!! Yesterday I had a call with a SC programmer and after many tests and check he has concluded that I’m the only one between all customers that has that issue.
Conclusion was… the problem is you PC… that is a super normal W10 . I’m really not satisfied about that.
For me it’s a bug. If other people has this issue please let us know so that we can ask SC for a more detailed check

My problem is occurring on an instance I have on scriptcase hosting, not on windows 10

Sorry it’s in Spanish, this was the response to a support ticket that I entered in the hosting portal. In short I must report it to the scriptcase team.

Great news guys !!!
I changed the php,ini file and set the max_input_vars = 20000 and now magically it works again
Lost about 4 months and the SC assistance said that the fault was only about my pc and not the excessive use of variables made by SC

Thank you, now is working.
