Drupal ImageMagick error

I have a Drupal site, and the ImageMagick plugin used to work fine. Now it won't convert images, and I have error messages all over the site. The main error is: * ImageMagick reported an error: convert: option requires an argument `-units'. . * An image thumbnail was not able to be created. Can somebody who knows Drupal try to fix this? All plugins are up to date. I long lost patience with Drupal myself, but I still operate one website that uses it. Rather than try to figure out why yet another error is appearing, hopefully somebody can come in and fix it for me. Too many competing plugins? Something not compatible with something else? Wrong settings? Something wrong with the server? I also wish to have a report on what and how they fixed it, in case the error pops up again in the future. Thanks in advance!
