On files managed by dolphins caching/compression (gzip_loader.php) deflate does not work properly. Files are delivered with "Content-Encodinggzip" but the ratio is 1 (no compression).
If you disable "Enable Compression For JS/CSS Files" deflate works on (bx_templ) css files but not (ratio 1) on js files.
By the way: Is anyone reading bug reports and entering them into trac at all or do I have to pay more just to report bugs?
