* Hi guys, I’ve just installed, when I’ll try it I saw a warning
* Warning: implode(): Invalid arguments passed in /home/naveguef/public_html/assinartvsky/
wp-content/plugins/ewww-image-optimizer/common.php on line 3098
* Here is my debug log [http://pastebin.com/9D1a5dXL](http://pastebin.com/9D1a5dXL)
* Thanks!

* Maybe this is because there isn’t `ewww_image_optimizer_aux_paths` options filled.

* Yup, I should have caught that myself. Thanks for the report, I’ll be sure it
gets fixed for the next release.

* Quick fix?
Replace `$ewww_debug .= “folders to optimize:” . implode( “”, $aux_paths).“
”;
* with
`if(@$aux_paths) $ewww_debug .= "folders to optimize:" . implode( "
", $aux_paths ) . "";`

* it won’t break anything, and the fix has not been released (and won’t be until
next week, because it isn’t critical)
