Yes, I can help you.

Change

public function on_intermediate_image_sizes_advanced_minus100_filter( $sizes, $metadata ) {

to

public function on_intermediate_image_sizes_advanced_minus100_filter( $sizes, $metadata = false ) {

That should fix your problem until next update.

Actually, when you apply server rewrite rules (see plugin help on settings page), browsers that do send “image/webp” in the HTTP: “Accept:” header, will be automatically served with “WebP” image, which is created both for “original image” and for “thumbnails” (other image sizes).

@ddur, please don’t write the same in all topics. This is the second topic.
The get_avatar() issue is only related to 1-2 plugins’ conflict, nothing more. So please don’t search this rare conflict in all support topics. Again, it has no any relation to the get_avatar() function ad this conflict is already fixed in upcoming version.

I’m trying to help your customer which have paid for your plugin and cannot use Simple History along with wpDisguz.

Thanks for future fixing of that issue.

BTW two topics is not all topics

For all hard to explain errors in other plugins (involving users and gravatars), caused by or related to wpDiscuz, test if problem disappears when changing user avatars to anything else than “Gravatar Logo” in Admin menu -> Settings -> Discussion.

Because wpDiscuz is doing some deep sh#t in handling ‘get_avatar’ filter and denies a problem (blames other plugins) for more than year now:

WordPress media editor, by WP design, preserves original image compression & quality as source for all theme sizes/thumbnails and for image editor (crop/flip/resize).
Compression applies only on images derived from original, not on original.
Else each “regenerate thumbnails” from compressed original image would further degenerate quality of derived thumbnails (would not be repeatable with same result as first time after upload).

In example, regenerating thumbnails from 50% reduced original would generate 50% of 50%, which is 25% quality.

In addition, original would loose quality each time is re-compressed again.

Solution: Do not use original on the www, use one of generated sizes/thumbnails or WebP image created from original.

In “thumbnail_image” function prototype, $filter is set to default value (FILTER_TRIANGLE), which is AFAIK, never set by calling functions.

So, if no caller is ever setting other values, default value is always used.

To have other value as default, in function “thumbnail_image”, change $filter_name = ‘FILTER_TRIANGLE’ to whatever value you want.
That is in deriving class file
…./plugins/warp-imagick/classes/class-warp-image-editor-imagick.php

You will find by WP accepted filter values in original class
…./wp-includes/class-wp-image-editor-imagick.php
function thumbnail_image

However, I would only increase jpeg image quality, in plugin settings.

In the code, you may try/experiment with increased image quality settings only when thumbnail image has smaller geometry/size. Then you may get better quality, but larger file. At your personal taste.
