It's a bummer that the maker of dfGallery doesn’t come with a solution to this problem.
The dfGallery possible fix earlier placed in this post does not work for me.
I emailed This Mister Marco a couple of weeks ago, but until now, no reaction at all. I bought a licence for dark matter pro, so I think a little support is in his place I think. But clearly he has a different idea on support for his sold products.
ps. His support text on his site:
If you need help with Dark Matter you can email me. However you're probably going to get help faster if you try the Pixelpost forum. I read this forum daily
. If you ask your question there you may get an answer from a fellow user before I even see it and other users may benefit from your question and the answer.
If you think you've found a bug in Dark Matter Pro, please make sure you:
Can properly reproduce the bug
Provide a detailed description of the problem
Provide information about the browser and operating system you are using
I cannot respond with proper action to incomplete or vague bug reports.
