Hi,
After a long search without any good solutions, I really need your help.
Since several days, in some pages of my back-office like category management, the category tree of my shop isn't displayed anymore. Find the example on the screenshot i joined.
I can't see where this problem can be from.
I did some update and added some modules but I don't remember of the lastest ones so I can't try to unistall them to see which one is inaccurate.
I turned on the error displaying mode but no errors detected by Prestashop.
It's not from the CSS either.
Did you have this issue?
If yes, how did you fix it?
Thanks in advance for your answer and your help.
