Plugin finding OLD Avif files & bugging

Hi,

Recently, my server provider was able to provide me a Litespeed server.

Before, I was on cloudflare free plan plus using a plugin Convertor for Media which created avif & webp files for images and used vary header to send the correct file to the corect browser.

When switching to Litespeed (I continue to use Cloudflare & update the dns with the new IP), I saw it was not compatible to do vary header, so I deleted the plugin, deactivated the Litespeed & checked in incognito mode & saw the filed loaded were no longer AVIF but JPEG

However, as soon as I press on use Litespeed server again, the AVIF files reappear & I have no idea how (I unistalled ythen plugin).

Is there something specific to be done at unistallation so that it goes to a pure jpg without header issue ?

Thanks,
