We are using OJS 3.1.2.4 and our site is https://threatenedtaxa.org
CrossRef XML Export Plugin is not depositing. It was working fine but yesterday when we published a monograph which was not depositing. I am getting blank page when I tried to download the xml. There is no error related to this plugin in the error_log.
The same thing is working when I deposited directly through crossref web form.
