All perspectives gone after restart

[ghost]

I restarted Emacs and met with this error:

[persp-mode] Error: Can not autoresume perspectives -- (error "Specified root is not an ancestor of specified window")

Now all my perspectives are gone. Please help!

hmm.... How did this happen? Did it happen after recent update of persp-mode? If not, try to update.

Anyway, looks like the problem with restoring a window configuration.
You can try to open a persp-auto-save[n] file in ~/.emacs.d/persp-confs/. See which file contains all needed buffers(search for def-buffer).
Then find def-wconf, put cursor on opening bracket >cursor here<(def-wconf,, press Ctrl+Space(start selection), then Ctrl+Alt+f this will select full (def-wconf ...) sexp, replace it with nil. Repeat this for all def-wconfs if needed.
After that save file in safe place and load it with Ctrl+c p l (or call persp-load-state-from-file). It will load all your perspectives, only window configurations will be lost.

I will try and restore tomorrow and revert.

Another workaround to try is to redefine the persp-delete-other-windows(paste this into *scratch*, select, and M-x eval-region):

(defun persp-delete-other-windows ()
  (let ((win (selected-window)))
    (when (or (window-parameter win 'window-side)
              (window-minibuffer-p win))
      (setq win (cl-loop
                 for win in (window-list nil 1)
                 unless (window-parameter win 'window-side)
                 return win)))
    (when win
      (let ((ignore-window-parameters t))
        (condition-case-unless-debug err
            (delete-other-windows win)
          (error
           (message "[persp-mode] Warning: Can not delete-other-windows -- %S" err)))))))

Then try to load perspectives from file.

redefine the persp-delete-other-windows

It's now in master fc129b7
