How to fix incorrect preview for WEBP in Flmngr?
Damien B.asked
I do not see previews for WEBP files in Flmngr window. Or file manager generates incorrect previews for them.

Flmngr uses php-gd library to process images. Despite this library claims support of WEBP for a long time, it is buggy until v. 2.2.4. Please update this library on your server and check its version by viewing phpinfo() function output. Pitfalls: be sure you updated the version of the library, not just a package of your OS. Sometimes it may require updating PHP version or OS version (in case of old Linux distributions) or manual copying a binary of the library from a server with a newer version.
