Does not save new fields

I have been using the Estatik plugin for some time without problems, I have recommended it to a friend and I am helping him with his configuration, but when I try to add new fields and click on the “save changes” button, I get a message on red where it indicates that the changes were not saved and as a consequence it does not add the new field, I have also tried to add new fields on my page and to my surprise it does not save the changes either “before if I did it correctly”, I reinstalled WordPress from scratch and I have installed only the Estatik plugin, and reviewing the error log several appear just installing the plugin and many when adding the new field.
