Problem solved. The Pocket (Read Later) Extension (3.0.1) in Firefox (18.0.1) disabled the Save changes function in Tablepress.

Java Plugin 7 update 11 was blocked in Firefox. Could that disable the Save button?

It might be a Firefox problem. Savings tables works in Internet Explorer, not in Firefox (18.0.1).

Preview also changed behavior. It now opens a second window/tab.
NB These changes were not present on another site with a similar mix of plugins.

Save changes > https://spijkerkwarts.nl/wp-admin/admin.php?page=tablepress&action=edit&table_id=1 does not do anything
