Once you have located the revision and restored it, you will then see the reverted content in your page/post ready for further editing if required.

You have now successfully restored your page/post to a previous state, and you are free to continue editing.

In the image above, you will see that we have reverted back from multiple blocks to a single block, but still within the Block Editor. If you would prefer to continue editing using the Classic Editor, you can save your changes here and then go back to your Pages/Posts list as per below.

From the Pages/Posts list you can click on Edit (Classic Editor)

You will then be able to view your content within the Classic Editor, which has successfully reverted the conversion from Classic to Blocks, as per the image below.

Personally, I would recommend using the Block Editor and not the Classic Editor. The steps above are just for demonstration purposes should you wish to revert back to show that it is possible to undo the changes.

If this training is now out of date, please let me know below or via PM, and I will get it updated for you.

If you have any questions about this, feel free to leave a comment below, and either myself or one of the other great WA members here will get back to you :-)
