Hello, I am trying to upload around 400 local cover images in a batch and I get a 500 error An error has occurred! *Error 500* This message may have been caused by any of the following reasons: - You made use of an external link to an item that is no longer available - You followed an outdated link e.g. from a search engine or a bookmark - You tried to access a page that needs authentication - An internal link in the client is broken and the page does not exist What's next? - Use top menu bar to navigate to another part of Koha. - To report a broken link or any other issue, please contact the Koha Administrator. Send email <library@ert.gr> I followed the instructions ( http://manual.koha-community.org/3.22/en/uploadlocalimages.html), created a zip that includes the image files and a .txt that connects each one with a biblio number. I even tried with only two cover images. I have no problem uploading one by one, but it takes time. I have Koha version 16.05.03.000 in Ubuntu 16.04.1 LTS Any help would be appreciated. *Vasiliki Mela* * ERT S.A. Hellenic Broadcasting Corporation Archives Department Library*
