As you can see image src path is correct, but the srcset is wrong.
<img width="150" height="150" src="https://birding.adventurebirding.lk/gallery/birds/_cache/Barbet-Brown-Headed-150x150.jpg" class="attachment-thumbnail size-thumbnail" alt="Barbet Brown Headed" aria-describedby="gallery-1-3188" srcset="https://birding.adventurebirding.lk/wp-content/uploads/birds/_cache/Barbet-Brown-Headed-150x150.jpg 150w, https://birding.adventurebirding.lk/wp-content/uploads/birds/_cache/Barbet-Brown-Headed-64x64.jpg 64w" sizes="(max-width: 150px) 100vw, 150px">
Anyone can help?
