Hi,
the theme v2.3.7 isn’t compatible with webp feature, please upgrade the theme to the latest v2.4.8. if the issue still persists, send me your backoffice access and FTP in a private reply.
Best regards.
Hi,
No, you need the module, but just theme v2.4.7 later can work together with it. so you need to upgrade the theme to the last version.
Best regards.
