Mobile not detected simulating a mobile device.

HI @apalcasabas0712,

You aren’t the only one having problems with W3 Total Cache, but unfortunately, I was never able to reproduce the same issue, it always works for me when I use the settings of W3 Total Cache to serve a different cache for mobile.
Probably, there are some situations when it doesn’t work. I suggest you open a thread on the support forum of W3 Total Cache.

Before opening a thread with them, I first suggest you:

• Be sure you have the proper settings to serve a different cache for mobile.
  I will tell you what always works for me.
  I go to Performance => Cache Groups
  I create a new group and call it for example “Mobile”
  I check the checkbox “Enable”
  I write this in the text area:
  
  *mobile
  *mobile*
  mobile
  
  And I can assure you, it always works for me, even on different installations with totally different plugins and theme. I’m surprised so many users have this issue with W3 Total Cache.
• Be sure there aren’t other layers of cache before W3 Total Cache, for example your server, or a CDN

Here you have a picture of the configuration that I suggested above:

In the picture you have also “MOBILE”…, but when I save the settings W3TotalCache keeps only what I wrote in the list. So, no matter, you can write only what I wrote in the list above.

If it doesn’t work, open a thread with W3 Total Cache and explain that you want a separate cache for mobile, but you see always the same cache.

Have a great day!

Jose

Hi Jose,

Thanks for the prompt response. However, the above suggestion doesn’t work and causes 500 internal server error instead, but I was able to fixed it by removing the added cache group for mobile in .htaccess.

I might ask my host provider if they can serve a different cache to mobile devices.

If the above doesn’t work do you have other suggestion to resolve this?

Cheers,

Arceline

Hi Arceline,

you are welcome.

but I was able to fixed it by removing the added cache group for mobile in .htaccess

What do you mean? Have you added the user agent into .htaccess instead of the W3 Total Cache settings?

Or do you mean after changing the W3 Total Cache settings you had a 500 error?

I really suggest you open a thread on the support forum of W3 Total Cache.

Have a great day!

Jose

Hi Jose,

I had the 500 error after applying the recommended changes to the W3 Total Cache setting.

Okay, I’ll open a thread on the support forum of W3 TC and will update you on their feedback.

Cheers,

Arceline
