IMHO I also think those guidelines are pretty stupid.
@chilaxnanananananana glad it worked! Been using it tons today again; glad there’s a fix but geez it’s really irritating.
This solved it for me. Didn’t expect it to work.
If you’re using Chrome, right-click on the greyed-out “Update” button and select “Inspect Element”. You will see something to the likes of:
<input name="save" type="submit" class="button button-primary button-large disabled" id="publish" accesskey="p" value="Update">
Just delete the word “disabled” and the update button will become clickable again. Click it and it should update.
Saved me reloading and losing work.
