Attachment cannot upload

[uart-aplex]

I am using this plugin with redmine 4.1.1.

I created a new category and a new article with 2 files attachment in PDF format, then will get 500 internal error..

Then I go back to previous page, this time I create new article with 1 PDF file attachment only without get any error,
But then I found there is no any file attachment in this article, it seems the file upload has some trouble.

i have something similar in 4.1.1. I can upload my attachment. But when i click the file i get a 404 Internal Error. I am able to download the file, but not able to view from hyperlink in redmine.

you may check the solution here :
#351

rename : /opt/redmine/apps/redmine/htdocs/plugins/redmine_knowledgebase/app/views/attachments/_links.html.erb

to become : _links.html.erb.bak
