PDF download view/ issue

My OJS setup was working fine and suddenly I got strange issue. PDF files load (view /download) upto some certain point like 30% to 80% and then progress stops. And after waiting long time it fail to view or download. I have checked everything else is working fine, the file permission etc. and I can see and open the files in web file manager. Any clue?

OJS 2.x version.
PHP 5.4

Hi @Muhammad_Tayyab,

Have you checked your web server’s error log?

Yes, I have checked all logs. No error in that

Hi @Muhammad_Tayyab,

Do you have a public URL to check as an example?

I played around on different settings like error reporting, show stack, CGI path, fopen etc. and reverted back but now i am getting 500 internal server error. I am working with .user.ini/ php.ini file to show the error

scroll down to check any pdf

just for info I am using godaddy windows server hosting

one more thing I found after enabling error detail:

PHP Fatal error: Call to a member function getRequest() on a non-object in
D:(folder_path_here)\html\journal\plugins\generic\usageStats\UsageStatsPlugin.inc.php on line 223

Thanks for your support. The problem is solved by disabling usage stats plugin
