Facing a lot of errors when trying to see the submissions of 2 Vol and issue 1

PHP Deprecated: Non-static method PKPApplication::getRequest() should not be called statically in /home/user/public_html/xyz.com/plugins/themes/academic_pro3/include/Core.php on line 530

It is a customized theme: academic_pro3

OJS 3.3.0-10

Hi @Devansh_Singh

Warnings like that are cosmetic and won’t affect the workings of OJS. However, if you’re running a customized theme as you appear to be, you’ll need to talk to the developers of that theme in order to get it updated. These warnings will probably become proper errors in future versions of PHP.
