[O] Org Publish Error

[Samuel W. Flint]

Hello all!

I'm currently getting the following error upon HTML export in publish
projects:

    cl-mapcar: Wrong type argument: sequencep, t

It appears it's coming up somewhere in the following:

      mapcar(#[257 "\300^A\301\"\207" [org-tags-expand t] 4 "\n\n(fn TAG)"] t)
      cl-mapcar(#[257 "\300^A\301\"\207" [org-tags-expand t] 4 "\n\n(fn TAG)"] 
t)
      apply(cl-mapcar #[257 "\300^A\301\"\207" [org-tags-expand t] 4 "\n\n(fn 
TAG)"] t nil)
      cl-mapcan(#[257 "\300^A\301\"\207" [org-tags-expand t] 4 "\n\n(fn TAG)"] 
t)
      org-export--prune-tree((org-data nil (section (:begin 1 :end 330 
:contents-begin 1 

Currently on GNU Emacs 25.3.1 (x86_64-pc-linux-gnu, GTK+ Version
3.22.26) of 2018-01-07, with Org mode version 9.1.6
(release_9.1.6-462-gb505a5 @ /home/swflint/.emacs.d/org-mode/lisp/)

Any/all help is appreciated.

Thanks,

Sam Flint
