Backoffice Product page tabs are not opening.

[Martino00]

When i try to open my products in backoffice only the first information tab is displayed.
I can't open any of the others.

In the developer tool i receive 2 error

2 days ago all was working good for the last year. And now suddenly?

I also can't enable or disable the cache.

Anyone a clue?

Which languages are active in your shop?

If you have gb it could be a familiar bug.

[Martino00]

Dutch as standard and french. No other.

Could it somewhere be a caching problem?

PS: myb prestashop version is 1.6.0.23

At the moment i have disabled my cache in backoffice
Also smartcache for CSS is off and smartcache for javascript is off.

This is how a page backoffice page with TinyMCE editing frames looks like in the browser's source code. Can you look for your version?

Look out for php version changes.

Server do updates, some give advance notice some don't
