Blank page in Frontend of OPS 3.3.0.15

Hi,

I have installed OPS 3.3.0.15 on my test server with PHP 7.3 and mysql 5.7 The installation went successfull and when I visit frontend it redirects to blank page. To debug this further I have set “debug=>On” in cofig.php file and then it throws following error.

Fatal error: Uncaught Error: Call to undefined method JournalDAO::getPath() in [[path]]/ops33015/cache/t_compile/65bfc3e024c2e9104f46e23b73376a9455e3df0e^51cfb9321c891ada9323e7942962579e7e4324d1_0.app.frontendpagesindexSite.tpl.php:56 Stack trace: #0 [[path]]/ops33015/lib/pkp/lib/vendor/smarty/smarty/libs/sysplugins/smarty_template_resource_base.php(123): content_64b7c7d0787109_23504481(Object(Smarty_Internal_Template)) #1 [[path]]/ops33015/lib/pkp/lib/vendor/smarty/smarty/libs/sysplugins/smarty_template_compiled.php(114): Smarty_Template_Resource_Base->getRenderedTemplateCode(Object(Smarty_Internal_Template)) #2 [[path]]/ops33015/lib/pkp/lib/vendor/smarty/smarty/libs/sysplugins/smarty_internal_template.php(217): Smarty_Template_Compiled->render(Object(Smarty_Internal_Template)) #3 [[path]]/ops33015/lib/pkp/lib/vendor/smarty/smarty/libs/sysplugins/smarty_internal_templatebase.php(238): Smarty_Internal_Template->render( in [[path]]/ops33015/cache/t_compile/65bfc3e024c2e9104f46e23b73376a9455e3df0e^51cfb9321c891ada9323e7942962579e7e4324d1_0.app.frontendpagesindexSite.tpl.php on line 56

However when I add new journal to it then the page redirects properly.

What could be the issue ?
