Broke site

Posted on 06 January 2023
Good range of options but never got to really try anything as it broke my site immediately upon publishing.
Ease of use
Simple to install, but, upon publishing the plugin, it broke the site.
I used this to: I decided to give it a go after reading the other reviews. I have used JCH for years and it's bulletproof, but, hey, why not try something else? It could do a better job. It didn't.
this plugin has all PWA features (offline mode, web push, services worker ...)
Ease of use
Really easy to use, install plugin go to plugins manager and enable it and that's it :)
documentation very detailed of all PWA features, also i do suggest some video tutorial this will help non experienced users.
I used this to: I used this for a client who want PWA features integrated, this plugin saved us time and money, thanks again to developer.
Funcionou perfeitamente em meus projetos. Com diversos recursos, inclusive até recursos que não existe em nenhuma outra extensão no JED.
Ease of use
Fácil de usar, porém tem que ter um conhecimento abrangente de todas as suas funcionalidades para configurar corretamente.
Não testei ainda, mas parece que responde rapidamente pelo Github, por ser uma extensão gratuito isso é muito bom.
Tem uma descrição simples sobre o que ele pode fazer, porém poderia ser mais detalhada para um usuário com pouco conhecimento.
I used this to: Estou utilizando para meus projetos pessoais e profissionais. Recomendo!
Funktioniert schon erstaunlich gut. Leider gibt es noch Probleme mit PageBuildern wie Gridbox oder SP-Pagebuilder.
Ease of use
SUPER! Extrem viele Einstellungsmöglichkeiten. Wünschenswert wäre, die Funktionen etwas mehr zu erklären.
Etwas detailliertere Funktionsbeschreibung wäre sehr gut.
Owner's reply: Hello, Can you file any issue here ?

Thank you
