Status update / summary:

There are two aspects to be dealt with separately:

Case 1:

• When using Imagify 2.2, WP Rocket 3.15.10+ must correctly adapt the WebP compatibility display. to do this, WP Rocket must take into account the new setting names of Imagify. This is to be dealt with here: https://github.com/wp-media/wp-rocket/issues/6468 for WP Rocket 3.15.10.

Case 2:

• When using Imagify 2.2+, versions of WP Rocket 3.15.9 and before must correctly adapt the WebP compatibility display. To do this, Imagify plugin must maintain the old option display_webp / convert_to_webp appropriately. This part would be handled here: https://github.com/wp-media/imagify-plugin/issues/850

@piotrbak, can I let you see the prioritiy for case 2? (this issue) Thanks

@MathieuLamiot I think we could close this issue and leave only this one opened. What do you think? https://github.com/wp-media/wp-rocket/issues/6468

[MathieuLamiot]

@piotrbak There are 2 issues to fix in 2 different places. One in Imagify, the other in WP Rocket. Unless you decide not to fix case 2, we should keep this issue open.

Update from Piotr here: If the effort here is more than [XS] we could close the issue, 1st scenario is the priority. We'd ask customers to update both plugins.

Isn't case 2 fixed by the update done in 2.2.0.1?

[MathieuLamiot]

That's the question raised here. Maybe, I don't know. It needs to be checked. What I am worried about is that we brought back display_webp option but do we keep its value updated?

[remyperona]

It won't be updated anymore, so is the expectation to keep it updated based on convert to AVIF enabled, and the filter?

[MathieuLamiot]

The requirement is that with WP Rocket 3.15.9 and Imagify 2.2.0.1+, the 3rd party WebP display must be accurate. That's the only way I see to keep backward compatibility with WP Rocket 3.15.9 and before ; otherwise the 3rd-party display won't be correct ; right? As @piotrbak mentioned, if it's more than [XS] (and I would add, if it complicated the codebase too much), we will discard this issue.
