Do you experience problems during downloading?
Check your connection in Status and Interface settings window.
Use Test Server in Config > Servers.
We will probably ask you to do a test using only basic settings.
Do you experience problems during repair or unpacking?
Enable +Debug logging in the Status and Interface settings window and share the relevant parts of the log here using [ code ] sections.
Is it possible to run a custom pre-processing script on one-or-more NZBs only if they are being added to the download list via the web UI?
I need to alter the detected NZB category from 'tv' (which SABnzbd quite-correctly assigns), to 'tv-unmanaged' (which is a category I use for tv episodes related to shows I haven't yet created entries for in SickChill/Medusa).
I use a different category for things added from sickgear ('sg' in my case) which allows me to retain the default 'tv' category for things added from the ui.
