Button save changes do not work

Hi!
I would appreciate some help to this issue, since I updated the last version of wordpress the button of save changes in the table is not working, so I am not able to edit my tables.
I have being reading some post about this issue, so I checked I have the last version of TablePress .12, I deactivated all the pluggings and it still did not work, I changed the theme to the tweenty theme and it worked then, so I made the changes and when I activated my theme again confirm that it did not work again.

Can you help me please to solve this problem?
Thanks ??

Maite.
