Hello . . . Today I opened claws-mail and the following error message appeared, "Addressbook Error Could not read addressbook index" To my knowledge nothing out of the ordinary happened. This app has been installed with daily openings for over a year or so. Is a reinstall necessary?
No, a re-install is not necessary. You'll have a backup file here: ~/.claws-mail/addrbook/addrbook--index.xml.bak rename it addrbook--index.xml. Closing this as it appears to be a question only.
