Hello to everyone who is in the know.
How to fix it?
When using the bootstrap3 theme (version 3.4.0.1) in OJS (version 3.4.0.5), I encountered one strange problem:
When I try to open the article details (Article Title) through the preview via Dashboard (Issues → Future Issues → Preview→ Article Title), the browser displays a blank page (Mozilla), the browser (Google Chrome) returns HTTP ERROR 500.
At the same time, if you use the default theme, everything works fine and the browser displays the necessary detailed information of the article (abstract, etc.) through the same Dashboard path (Issues → Future Issues → Preview → Article Title).
I found the following errors in the PHP server error logs:
