Hallo Peter
Have updated to J 4.3.4 and something is not working as it should.
Updated to latest Modals 12.4 Pro

In my article I am using this Modal instruction (worked fine on J 3.10.12, but not in J4)
{modal gallery="images/Over-ons" title="... Engineering, ons bedrijf " thumbnails="all"}{/modal}

Getting this error on the frontend:
Reading Exif data is not supported by this PHP installation.
(I am using php 8.0)

Error.log :

Can you help me on this one?

Frank

I think you should update your J4 docs as well then ...
(to PHP 8.1 minimum)
