Problem add New couriers

[bonfanticonsulting]

When I try to add a new couriers always redirects to the admin login page.

 

I cleared the cache but nothing.

 

How can I fix or restore?

 

Thank you.

here we want to disable 3rd party modules | overrides

 

once disabled then see if you still have issue...if you do not then it's a 3rd party module and/or override...but gives you clue.

 

if after this and still not work, then enable ps debug mode, search if you do not know how to enable...then recreate and see if php error..also check hosting error log.
