Code:
Exception: Trying to set entry (chapterstotal) value(1/1) to column (#totalchapters) failed (invalid literal for int() with base 10: '1/1')
You likely have something setting chapterstotal to an integer column. '1/1' is not an integer, so it fails.
according to defaults.ini, chapterstotal is only suppose to list the last part of that (chapterslashtotal is the full one), so Id look for any replaces that change that.
