Hi Csaba,<div><br></div><div>It's shame you don't post your yaml, but I suggest:</div><div><br></div><div><div>globals:</div><div><span style="font-size:10pt"> image:</span></div><div> formats:</div><div> png24:</div>
<div> format: image/png</div><div> mode: RGBA</div><div> colors: 0</div><div> transparent: false</div><div> resampling_method: bicubic</div><div><br></div><div>And use this image format in your cache settings.</div>
