Is there a list of plugins that do not allow you to pass the Mobile friendlytest

Oh goodness no, there are currently 37,524 free plugins in just the official directory, and plenty more elsewhere. https://www.ads-software.com/plugins/

I highly doubt there will ever be a definitive list, it will just have to be trial and error.

Plugins can be affected by your theme too, you might want to also ask for a list of plugins that cause incompatibility with each theme too – calculate that James!

Oh, that would be a nightmare, all of the plugins, all of the themes, all of the combinations.

Yeah, stick to trial and error for that. ??

Guys thank you for your feedback. Much appreciated.

I found something even weirder on my site:

when I pass the test without the www. ( https://cubavisa.uk ) it passes the test.

when I do add the www. does not ( https://www.cubavisa.uk )

Any ideas why?

thank you before hand.

Are you using the checker at https://www.google.com/webmasters/tools/mobile-friendly/ ?

@ james huff yes, that is right

Ok, so here’s the problem: https://cubavisa.uk/ is redirecting to https://www.cubavisa.uk/

Note the lack of HTTPS, that’s crucial.

Browsers do not cache content over HTTPS, making the HTTPS site much slower for repeat visitors, and potentially lower in score than the HTTP site.

I’d recommend leaving the site at HTTP, and only using HTTPS on pages that pass sensitive information (login forms, shopping carts, etc). If a visitor wants HTTPS for the entire site, they’re already using a browser extension like HTTPS Everywhere, which forces it for them.

Thank You James, its seems fine now.

You’re welcome!
