    Hello!

    I have Joomla 5.4.0 with JoomGallery 4.2.0. I show images with Category View and clicking on image or title user can see image in Lightbox. But, on my site Lightbox does not work, all images shown as ASCII code. On browser error console i see an error:

    Uncaught ReferenceError: lgHash is not defined
    callback https://web.ee/media/com_joom…id.js?505fa2:60

    Hello!
    Perhaps also important for the programmer:
    -Which JG version did you update from to 4.2?
    -Or was it a fresh installation?
    -Which PHP version are you using?
    -Do you have a link to your website with JoomGallery?
    -Does the error occur with all images?
    - What image format are you using?

    Wir sind auf der Suche nach Helfern für die JoomGallery 4 Entwicklung!

    Melde dich bei Interesse bei mir (Elfangor93) oder bei mir.

    Hello!

    I had the same problem as I today updated Joomgallery to version 4.2. Fortunately I made a backup before updating. After restoring the Joomgallery version was 4.1.1 again and everything was alright again.

    By the way I use JoomPlu PRO for showing thumbnail- overviews of categories and Lightbox for single view of images. An example: https://kgv-calw.de/themenportal/f…n-calmbach-1952.

    Greetings
    Michael

    Ich kann das Problem bestätigen und auch ich nutze JoomPlu Pro.

    Auch war das Plugin nach dem Update auf JoomGallery deaktiviert, aber es lies sich einfach wieder aktivieren.

    Are you using template overrides? If yes, then you need to update your override file. There was a change in the category and gallery view template.

    Hallo,

    seit heute gibt es ein Update des Plugins JoomPlu Pro auf Version 1.2.1. Das hat bei mir die Probleme mit Joomgallery 4.2 und der Lightbox-Ansicht behoben.

    Herzlichen Dank und Grüße
    Miba

    Ich hoffe die Updates erleichtern euch die Arbeit mit der JoomGallery.
