Hi,
Software: Open Monograph Press 3.3.0.4
In order to get indexed by Google, I inserted Sitemap URL (https://omp.akademisyen.net/index.php/akya/sitemap) to Google Search Console and waited for being processed. Unfortunately, the sitemap URL couldn’t be processed and I see that sitemap url returns a blank white page with 500 Internal Server Error.
When I disabled DOI plugin, sitemap URL is generated properly.
DOI is enabled for Monographs, DOI prefix has been entered, and default pattern is selected in Plugin Configuration.
The php-error.log contains following lines;
[21-Mar-2021 00:49:38 Europe/Istanbul] PHP Fatal error: Uncaught Error: Call to undefined method SubmissionDAO::getLatestRevisionsByAssocId() in /home/omp/public_html/pages/sitemap/SitemapHandler.inc.php:46
