Hi,

Now i've updated Hikashop to 2.6.2 and i have an issue when i manage the orders;
i have an error "403 access forbidden"
You can see where i have the error on my screenshot.
Could you help me to fix this issue?
Thanks a lot

Hi,

We're not able to reproduce the problem.
Are you sure that it's not because you were logged out from your backend when you clicked on the edit icon ?
Are you able to reproduce the problem again ?

Hi,
i don't know what happened, but yes i was logged in, i'm sure.
I had just updated the site.
Yesterday i'd tested the site a lot of time with the same error always.
Maybe something wrong on a cache... :blush: i don't know...
I've just tried this morning and it works fine.
I'm sorry, excuse me
Thanks a lot for your help
My best regards
