An error maybe related to some deprecated function.

it looks like WordPress Core may still be using a deprecated function. See line 224 [here]​https://github.com/WordPress/WordPress/blob/master/wp-includes/class-wp-locale.php

Welcome to WordPress core trac

Replying to birgire: yes it's already done thank you

@pcnador great, glad to hear it

The get_bloginfo() function is not deprecated.

This issue seems to be plugin related, where the function might be used in some unexpected way?

One way would be to see what happens without that plugin.

You might also consider contacting the plugin support?

yes you're right I'll try it and see

Welcome to Trac!

As noted above, get_bloginfo is not a deprecated function. It appears that in your case W3TC is calling it early (not loaded yet). Please contact the W3TC dev team.
