Design editing can not be saved.

Not saved when you try to save the addition of CSS code by pressing the 'Save changes' button.
Button is much will remain rotated.

Our sincere apologies.

We have this issue last day but this is already resolved.

I tried it on a cloned version of your form and it is working for me.

Please try to do the following and see if this helps.

1. Make a cloned version of that form https://www.jotform.com/help/27-How-to-Clone-an-Existing-Form

2. Remove the No script widget, mobile responsive widget and preview before submit widget on the cloned form.

3. Open the Form Designer and make a small edit and save it.

I also think that the 3 widgets have caused some conflicts on the designer. Feel free to add them once you are done with the changes.

Let us know if this doesn't work for you.
