OJS 3.1.2 - can't schedule article for publication

Hi,

My website showed the following error: ‘An unexpected error occurred. You may have been logged out. Please reload the page and try again.’

This is what apache logs showed:

“PUT /index.php/margenes/api/v1/submissions/1029/publications/867/publish HTTP/1.1” 500 903 “https://x.x.x.x/index.php/margenes/workflow/index/1029/5

“GET /lib/pkp/lib/vendor/tinymce/tinymce/skins/lightgray/skin.min.css.map HTTP/1.1” 404 3762 “-”

I disabled ORCID plugin and installed allowmethods module too, but it didn’t work.

OJS 3.2.0-2
Apache/2.4.25 (Debian)
PHP 7.3.11-1~deb10u1 (cli)

Yassiel
