Problems that can arise with the WissKI IIIF/IIP module.
## Error: No response from server /fcgi-bin/iipsrv.fcgi
This is most likely due to a misconfiguration in the `WissKI IIP Image Viewer` field formatter.
Possible steps to fix this:
1. Go to `Structure`→`WissKI Entities & Bundles` and edit the bundle that has the problem
2. Click the `Manage display` tab
3. Make sure the `IIIF-Server` and `Directory prefix` settings are set correctly
- you can look these up on the server in the IIIF server config (usually located in `/etc/apache2/mods-enabled/iipsrv.conf`)
- sane defaults are:
-`IIP-server`: `/fcgi-bin/iipsrv.fcgi`
-`IIP Filesystem Prefix`: leave blank (on OiN it's `/data/www/wisski_base/sites/`)
4.**VERY IMPORTANT**: In case that the bundle that's causing problems has sub-bundles also check their `Image` fields for the correct settings if they use the `WissKI IIP Image Viewer`. The formatter passes the settings to JavaScript. Since sub-bundles are rendered after the main bundle, the settings from the main bundle are overwritten with those from the sub-bundle.
