I’m not really sure about these question

Not sure where I can check that.
I just know that it’s all working fine on most of my MODx copies at same server and it all was working fine on the ones I’m having problems right now. I just set up MaxiGallery and EditArea in last place it happened and after that the issue came.
In different places I can’t remember after what exactly I added when it stopped working but in this last MODx setup I remember I tested that everything was working and then I added Maxigallery and EditArea and it stopped working. Removing MaxiGallery and EditArea didn’t help, too. Really-really weird, I have to say...
