Reduce or disable the undo/redo capability

The History Manager works behind the scenes to enable the Undo/Redo feature in the Beaver Builder editor, accessed by going to the Tools menu and clicking History. By default, the History Manager is set to store a maximum of 20 states for the page or post you're editing.

In some environments the History Manager can cause the editor to act sluggish and using the Undo/Redo functionality to be very slow. In particular, there are two interacting factors that can cause the default maximum of stored History Manager states to be less than ideal: โ€‹

  • Your site is on a shared hosting environment where the server is slow.
  • The page has a large number of rows and modules.

In these cases, it can be helpful to reduce the number of states stored in the History Manager or disable it entirely. โ€‹

Reduce History Manager functionality#

To reduce the number of states in the History Manager, add the following line to your wp-config.php file. Change 10 in the example to the number of states you want the History Manager to store. โ€‹


Try reducing the number of stored History Manager states to 10 and check performance, then tweak up or down.


Test and tweak the number to suit your environment.

Disable History Manager functionality#

To disable the History Manager entirely, add the following line to your wp-config.php file. โ€‹


With a value of 0, the history is erased when the Beaver Builder editor is opened and no new events are created for the page, so if there are any admin performance problems at that point, the problem lies somewhere else.
