Problem with Providence lightbox

In Providence, when accessing an enlarged image in the Lightbox overlay, the initial enlarged images presents itself fine. However when zooming in and panning around for an even larger detail, an error is thrown, “an error occurred when trying to access /providence/index.php/Detail/GetMediaOverlay/context/id/167/representation_id/363/overlay/1: Invalid controller path." The image disappears and is replaced by a path presumably for the detail image more enlarged. Any ideas why this is happening? Thanks!


  • I am running into the exactly same problem. Debian 9, providence 1.7.6, git commit a358ebbd.
    Lightbox was working in the past (before summer?), but I cannot specify which system update or git checkout caused this issue. Any clue on your side, rsteinert?

  • Hi Felix -- Since it is on the data entry side, I am living with it....Not ideal. Will post any findings I have when I get some time to investigate.

  • Any updates here? We are running into the same issue.

  • In your media_display.conf file check the "images" blocks and make sure no_overlay = 1 is set. Eg:

    images = {
    mimetypes = {image/jpeg, image/tiff, image/png, image/x-dcraw, image/x-psd, image/x-dpx, image/jp2, image/x-adobe-dng, image/bmp, image/x-bmp},
    display_version = medium,
    alt_display_version = medium,
    viewer_width = 100%, viewer_height = 100%,
    ** no_overlay = 1,**
    use_universal_viewer_for_image_list_length_at_least = 12,
    download_version = original,

        viewer = TileViewer
  • OMG super fast @seth! Thanks! I'll try this.

    I just went in and changed the images to use the UniversalViewer instead of TileViewer, and that also solved the problem.

  • Thank you, Seth! That is great! Works really nicely. Will this setting be preserved when upgrading Providence or should we make a note of it to change manually?

  • It will be preserved when upgrading.

  • Seth, it seems that TileViewer is no mor working on v 1.7.7.

  • Works for me. You'll have to be more specific.

  • Here the details: Mirador and Universal viewers work fine. TileViewer loads but does not load the image.
    The media_display.conf is the original delivered withg v. 1.7.7 apart from switching from UniversalViewer to Mirador.

    media_overlay = {
    images = {
    mimetypes = {image/gif, image/jpeg, image/tiff, image/png, image/x-dcraw, image/x-psd, image/x-dpx, image/jp2, image/x-adobe-dng, image/x-dcraw, application/dicom, image/bmp, image/x-bmp},
    display_version = tilepic,
    alt_display_version = large,
    viewer_width = 100%, viewer_height = 100%,
    download_version = original,
    no_overlay = 1,

        viewer = Mirador,
        #use_universal_viewer_for_image_list_length_at_least = 3
        #use_mirador_for_image_list_length_at_least = 3
  • Maybe v. 1.7.7 misses some code you get from previous versions?
