Before updating to my web server, I try to update on my local server on my computer.

I started by installing my site on my computer and everything worked well.

Afterwards, I transferred the update files to the local directory.

After this transfer, I tested the site.
Everything seemed to work well in consultation, but not if I'm trying to post an ad.

When I want to post an ad, I block at the first step. Categories do not load

How to fix this problem

Thank you
