Hello, I just put my website from MAMP to ftp (PHP 5.4.28) and can’t access the panel.
www.kioskpunktsechs.de
The website is in a subfolder (I think).
All pages work but the login is also broken.
Can’t use method return value in write context
Appreciate help 
Erik
Sounds as if you are you plugins that require a higher PHP version?
Hm, I’m not using any plugins but the ones that were already in the starterkit.
But do you think the problem are the plugins?
The Starterkit does not have any plugins.
What Kirby version are you using? There was an issue with old PHP versions in Kirby 2.5.7 that was fixed in 2.5.8. However, I recommend you update to a newer PHP version, as 5.4 has long seen its end of life.
Ok, it shows the login panel now, but can’t go any further.
I’ll just contact my hoster.
Many thanks!
