[Resolved] Uncaught TypeError: Illegal offset type in isset or empty in

This is line 10

And this is the template code of image-text-header:

By mistake, we executed Settings > Media Translation > Start before installing the media translation add on. We then installed it right after that and thought it would solve the problem

But I also wonder how it can be that a seemingly critical function can shut down everything

And what possible sources of error could there be on the theme side?

Before we executed the Media Translations via "Start", everything ran smoothly with our theme. The entire content was visible for DE and EN and everything worked, except for 2-3 things that I put in the initial ticket.

What would help you to investigate further here?

We have now reset the entire site to a previous state via backup in order to be able to continue working. But I will keep that in mind, thank you.

Heading back to the initial ticket, when we would like to show different images on specific pages / fields, what do we have to do to achieve this without arriving at the same error?

Is it enough to install the media translation add on (without restarting the media translation via "start" in the wpml settings)?

Our aim is to only show different images on a few places on the page. So not everything should be duplicated. In addition, we would only like to make the changes within the editing of the page and not in the wpml translation editor. (Screenshot attached)

For URLs it worked when setting the translation option to not translate. So for images it's not possible like this and only works with the media add on?

Ok, thank you.

Then you can close the ticket and if we come back to it, we will open it again if possible.
