Hello, I have a problem with my publishing workflow. Here is the setting of my variable org-publish-projet-alist in my init.org (setq org-publish-project-alist '(("fil-web" :base-directory "./" :base-extension "org" :publishing-directory "./" :preparation-function update-all-dblocks-before-exporting :publishing-function org-html-publish-to-html :html-extension "php" :body-only t :html-postamble: t :html-postamble-format : "" ))) This worked nicely until a few days ago: starting from page.org, it would produce page.php as expected. Today I upgraded my system from ubuntu 18 to ubuntu 20. I have GNU Emacs 26.3, and org-version is 9.3.1 Now, when I want to publish, it gives me the following error : Publishing file /home/lipari/Documents/corsi/IoT/portail/portail-master-info/portail/ue-M1S2-COA/ semainier.org using ‘org-html-publish-to-html’ org-combine-plists: Wrong type argument: plistp, (:base-directory "./" :base-extension "org" :publishing-directory "./" :preparation-function update-all-dblocks-before-exporting :publishing-function org-html-publish-to-html ...) Unfortunately, this completely breaks my long-time functioning workflow for publishing the details of my course on the University portal. Can someone please help me sort out the problem ?
