Hello,

I'm developing a plugin that just convert pixel values to em but I'm facing this error (as title) when I run the script on Sigil 0.8.7 on my friends computer. Note that this script work fine with 0.9.10 on my computer. He said, he need the old version because there is some error that the new version skipped when he checked the ePub so he don't want to switch.

Someone can help me how to fix this please ? What can cause the problem in these version ?

Thanks.

Spoiler:

This is the content of plugin.py
