Hi @Ptran,

I can’t replicate that problem – are there possibly any modifications to the code? Are there any warnings above that message in the log? Do you have your PHP configuration set to send errors/warnings to the browser, or just the log file?

hi Alec,
I haven’t modified anything else but the config.inc.php file to turn on the debugs. There are PHP Notice above the errors.
[Fri Dec 06 10:17:13.001415 2019] [php7:notice] [pid 20278] [client 10.25.8.2:44466] PHP Notice: Deprecated call without request object. in /var/www/ojs/lib/pkp/classes/template/PKPTemplateManager.inc.php on line 872, referer: http://xxx.xxx.ca/index.php/yptc/submissions

I don’t have PHP configration set to send errors/warning. I got this errors from the apache log.

Suggestion?
thanks
