Deprecated notice in PHP 8.2 – stripos

lvckyrain

Hi,

I’m getting a deprecated notice in Query Monitor related to BeTheme when running PHP 8.2.

Here’s the full message:

stripos(): Passing null to parameter #1 ($haystack) of type string is deprecated

wp-includes/functions.wp-styles.php:90

The stack trace shows that the warning originates from:

wp_add_inline_style()

→ /wp-content/themes/betheme/functions/theme-head.php:714

→ mfn_styles_inline()

It looks like mfn_styles_inline() sometimes returns null, which is then passed to wp_add_inline_style().

Starting from PHP 8.1, passing null to stripos() triggers this deprecated warning.

Could you please check this and update the function so it always returns a string (even an empty one),

or add a safeguard before calling wp_add_inline_style()?

Thanks a lot for your help

Phil

Hi,

I have passed it on to the dev team, and we are reviewing this.

Best regards
