Problem with the the saving of a ChronoForms

I installed the chronoforms module on my joomla site and I am having problems saving a form.
So far, I could do some changes which were always saved but over the past few days, when I try to make a change (url : administrator/index.php?option=com_chronoforms5&act=edit&id=33) for example in the local tab, it doesn't get saved and I expelled from the back office without having the changes saved (url : administrator/index.php?option=com_chronoforms5&act=save&save_act=apply).

FYI, I look-up the diagnosis and it gives me 2 issues ad 1 notice.
I also created a new form by following the same examples as the one that doesn't work but as soon as I save (example in Designer) I have the same problem.
I also increased the size "max_input_vars".

Can you please help?

Thanks in advance.

Hi aliZjoomla,

You've found the right FAQ - please check in the Site Admin > System Info > PHP Info tab what the actual max_input_vars setting is.

You may need to check with your web-host if that has not increased.

As I said before, I did the the thing the right way : I have already increased : the max_input_vars size / suhosin.post.max_vars, suhosin.request.max_vars, from 1000 to 3000 then to 5000.
However it doesn't help.
Do you have another option ? Thank you in advance

I think I need explanations about the two following issues (see attachement) ? Could you help ? Thank you

Hi aliZjoomla,

These are probably not important :-(

If you are using the Simple Wizard you can change the Setup Mode in the General tab to Advanced and you will see these icons on the form actions with more description.
