Home page error in ojs-3.1.2-4

How to find ojs-3.1.2-4 home page’s php file
I need some changes in home page. Please give me solution

Hi @Pradip_Dhakal,

For installations with only 1 journal it’s journal index template: https://github.com/pkp/ojs/blob/master/templates/frontend/pages/indexJournal.tpl

and for multijournal installations there is also index site template (site-wide homepage with a list of journals): https://github.com/pkp/ojs/blob/master/templates/frontend/pages/indexSite.tpl

If you mean controller, take a look at IndexHandler: https://github.com/pkp/ojs/blob/master/pages/index/IndexHandler.inc.php
