If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I checked your forms and was able to save them without any problem, I can see you're using our v3 builder and what I would suggest you is to check your session if you experience the problem again, if the session has expired your form will not be saved and will end up in the saving process to get stuck.
If after checking your session you're still unable to save your form, pelase try with another web browser, computer or internet connection, may be that there is something blocking the JotForm resources and this is why the form does not save.
You may also check the web console in order to find if there's an error, these keyboard shortcuts will help you to get it:
Mac: Command + Option + J
Windows: Control + Shift + J
