Hi and thanks for your quick replies!
I used the div from 3D.WP.Tag.Cloud.S.php version 5.1 line 128
<canvas title="<?php if($tooltip != ''){ echo $canvas_tooltip;} ?>" id="tag_canvas_<?= $inst_id; ?>" width="<?= $width;?>" height="<?= $height;?>"></canvas>
and added style="width:50%;"
and replaced s.functions with version 5.1
when I revert the changes and use the original version 5.2.1 the canvas does not change.
The cpu load was a browser issue, sorry.
btw I like to work late too
thanks again!
