After Update a Joomla Site from 3.7.5 to 3.9.8, site won't load and display the following error message :

_**Warning: Creating default object from empty value in /public_html/libraries/cms/application/site.php on line 540

Warning: Creating default object from empty value in /public_html/libraries/cms/application/site.php on line 540
Error displaying the error page: Call to undefined method JLanguageHelper::parseIniFile(): Call to undefined method JLanguageHelper::parseIniFile()**_

Solution :

Rename libraries folder to libraries.old
Copy libraries folder from 3.9.8 full package zip to your site.

Note :

if you have any custom libraries sub-folders in libraries.old, copy them again into the new libraries folder.

Result :

Site loads successfully
