I am trying to use Script-Fu Layer effects and they are all grayed out. I tried to use a selection, then no selection, made sure it was on RGB. I don't know what else to try. It always worked before. HELP please.

Isn't there a python version of this? Maybe that would work better. Just had a thought, has your layer got an alpha channel?

I don't know if there is a Python version but this Script-Fu has always worked before, then all of a sudden it doesn't. it shows all the stuff there but they are gray.

EDIT: I just googled Layer effects and downloaded them again and pasted it into my scripts folder and now they are not gray anymore. strange huh!

There are a couple of python versions http://registry.gimp.org/node/186?page=1 Make sure you download the right one though.

Possible reasons:
- image not in RGB mode
- layer has no alpha channel
- no layer selected (channel selected instead)
- floating selection

thanks, I solved it by downloading the script again. I can't understand why they were all listed but gray, they shouldn't have shown at all if the script wasn't in my folder, (would they?)

Those scripts are written such that they are only available if the active drawable is a layer which has an alpha channel. In other words, the menu commands will be grayed out if you are editing a mask or channel, or if the layer you are editing does not have an alpha channel.
