Hi, got this code on my site

{show device="desktop"}
<a href=" sun.eduzz.com/1444983?a=87651510 " target="_blank"><img alt="Mamãe faz grana" src="images/mommy_grande.webp" width="1280" height="200"></a>
{show-else}
<a href=" sun.eduzz.com/1444983?a=87651510 " target="_blank"><img alt="Mamãe faz grana" src="images/mommy_pequeno.webp" width="450" height="200"></a>
{/show}

Getting this error:

0 Class "RegularLabs\Library\MobileDetect" not found

How can it be fixed?

So simple... Its working now, thanks.
