i have the problem, that the search on my homepage doesnt work anymore(i do not know, since when). in frontend i enter a searchword, hit search and got only redirected to startpage of homepage, no error on console. then i go to the backend, go to components -> search and get the error message:
Call to undefined method Joomla\CMS\Application\AdministratorApplication::getLanguageFilter()
then i went to fossies.org and searched for that function.
the function getLanguageFilter() is not in AdministratorApplication.php, but in SiteApplication.php...
has anybody a hint why backend -> components -> search is pointing to the wrong path?
i tried reinstalling joomla corefiles with no success...
because of using falang, i deactivated falang content search for test and activated joomla content search, no success...
joomla 3.8.8, all components/modules/plugin are up to date...
kindest regards, frank
