Custom open and close icons

Yes – changing line 21 fixes the problem, thanks. I’ll look out for that change too next time there’s an update to the plugin ??

Okey, we will put that fix into the next installer too!

About the colorize: it wasn’t really made to use it with the custom icons, that is why it only works with png files, also it doesn’t really changing the colors to the one you select, but it works that way, that we put up icons only with specific green colors into our backend, and when you select for example red, it will calculate the difference between the green and red colors, as a number, and it will shift the color of that image as much, as the calculation was, so if I would replace the green icons with blue ones, those won’t be red, when red is selected but green. You should rather give colors to your icons in an image editor. If the images have more colors, it could be done for example in photoshop with the color replacement tool.
