When it refuses to save
Read the message, fix the problem, and keep your edits while you try again.
If a save fails, the message stays on the page and your edits stay in the editor. Read it before leaving or refreshing the screen. The save is complete only when the button says Saved.
A required field is empty
The message names the field that needs attention. Press its name to open it, correct the value, then save again. Some fields need a particular kind of value, such as a number or a web address.
Something else is using this address
Two entries of the same kind cannot share a slug. Change one of them — the slug box sits under the title.
Something still points at this
You cannot delete a picture that a page is using, an entry that another entry links to, or a kind of content that another kind refers to. The message tells you what is holding on.
Remove or replace those links first. If you only want a page hidden from visitors, use Take off website instead of deleting it.
A connection or permission problem
If the message reports a connection problem, check your connection and try saving again. If it says your account cannot make the change, ask your site manager. Keep the message so they can see what stopped it.
An Inky change did not apply
The error stays on that proposed change, and its button becomes Try again. It has not been applied. Fix the problem named in the message, then try again, or ask Inky to prepare a corrected change. Apply all stops at the first failure; earlier changes marked applied have already been saved.
