Hello,
I have OJS 3.2.1.1 installed, with 6 journals working correctly
When I try to get the report of the Pkp Usage Statistics Report of one of my 6 journals, I get an http 500 internal error, with the 5 other journals, the plugin works fine.
the server (Linux Debian Jessie - apache 2) error_log dont give a useful indication, here is what is mentionned in the log file :
“ojs2: 404 Not Found
PHP Notice: Trying to get property ‘single’ of non-object in /var/www/html/plugins/generic/citationStyleLanguage/lib/vendor/seboettg/citeproc-php/src/Rendering/Date/DatePart.php on line 227
