Can’t remove featured image from page

by Dennis Asp·4 years ago

Great theme, but it sucks that you cannot remove the massive featured image from the top of your pages

Simple and intuitive

by lektuvs·5 years ago

Uncomplicated, intuitive, but not poor. Even the free version has everything you need for a blog.

Bin begeistert

by binifada·5 years ago

Ich nutze das Theme jetzt seit ein paar Monaten. Als Anfänger in WordPress ist der Beginn natürlich etwas zäh. Aber nach kurzer Einarbeitung kam ich mit “Poseidon” immer besser zurecht.
Ein super Theme aus deutscher Hand! Weiter so!

Страхотен изчистен дизайн

by catzarov·6 years ago

Ползвам тази тема в комбинация с едно приложение, което създава от моя сайт приложение за мобилно устройство. Темата изглежда перфектно, която се визуализира в webview на телефони и таблет. Днес успях да и направя публичен превод на български език 😉 така, че ще ви бъде лесна за ползване, когато езиковия файл се валидира.

Genau richtig

Schlicht und sachlich. Unkompliziert.
