I found an issue with this plugin that was breaking the loading of user template functions. This is discussed in
https://www.mobileread.com/forums/sh...d.php?t=347818.
The issue is that the plugin was reloading the database when it was initialised or the library was changed. When I looked at the code, this was not needed in the two places it was done. And in the place where the database was needed, it was using the current database instance correctly.
I have attached an update beta of the plugin that fixes this. I haven't done much testing of the plugins function, but, it seems to work.
