Hello there,
I have updated another website, it seems to work but when i try to login i get the following error...
0
Call to undefined method Joomla\CMS\Application\SiteApplication::isAdmin()
I have looked up the error and it seems that in PHP8 isAdmin is deprecated and has to be something like isclient(admin) or something... (i watched a youtube video about this lol)
But i dont know where to find the file to adjust this... maybe someone can help me fix this?
Site is here: http://bp100.vulperia.synology.me
credentials are in the hidden content...
