Hi,
For me, after manual update of latest IMP:
# cd /var/www/horde
# sudo -u www-data composer update
# wget https://github.com/horde/imp/archive/refs/heads/FRAMEWORK_6_0.zip
# unzip FRAMEWORK_6_0.zip
# cp -rf imp-FRAMEWORK_6_0/* vendor/horde/imp/
# chown -R www-data:www-data vendor/horde/imp/*
"source email" works OK.
I only have errors on:
- "Download button" of a file (pdf in my test): Looks like there’s
a problem with this site. The server at server.domain.com sent back an
error: 500 Internal Server Error
- "Download All (2 Attachments)": A fatal error has occurred. User
is not authenticated.
Works OK:
- Click over each file name
- View source
- Text View
- View Related
- View Alternative
- View images
Best regards
Angel
