OJS Login page giving 404 not found error


Today I have upgraded to and it was working fine but suddenly login/register/submission pages are not working.

I see the following errors in the php. Please help me solve this issue.

Warning : in_array() expects parameter 2 to be array, null given in /home1/jott/public_html/lib/pkp/classes/core/PKPPageRouter.inc.php on line 226

Warning : Cannot modify header information - headers already sent by (output started at /home1/jott/public_html/lib/pkp/classes/core/PKPPageRouter.inc.php:226) in /home1/jott/public_html/lib/pkp/classes/core/Dispatcher.inc.php on line 255

404 Not Found

Hi @latha_ojs,

How did you perform the upgrade?

Does this error appear right after the upgrade? I mean, did 3.3.0-6 worked fine for a while?

Also, did you have any environment changes in your server, like PHP version?
