Please don’t post any bugs here - use GitHub. This issue is because you are trying to use this theme alongside with JATS Parser Plugin. This theme shares with the plugin the same classes, which results into error. Just disable JATS Parser Plugin:
Great work @Vitaliy! It’s really exciting to see what you’ve been able to do with the Theme API. I’m really glad to see the community stepping in to provide theming options.
Hi @Vitaliy,
Thank you very much for this much awaited theme !
I was wondering if you were planning to include in the future parsing for the JATS “sub-article” tag.
This tag is especially useful for publishing referees’ reports and authors’ response in an open peer review process.
In open peer review process, this tag follows the /back tag and does contain any elements just like an article. See for instance xml file at https://f1000research.com/articles/7-90/
(An alternative solution, though less compliant with the JATS, is to include referees’ reports and authors response as supplementary sections after the discussion section, in the body of the article)
Bootstrap 4 is already inside the theme: https://github.com/Vitaliy-1/oldGregg/tree/master/bootstrap
If your hosting provider meets requirements for OJS, the theme will work.
Although, I don’t remember if I have used there PHP 7 features. So, maybe you will need PHP version 7.0 or higher.
