Can't publish Hook

Unfortunately I don't have any ideas why that would be the case.

I didn't have to use Ads Inserter plugin in my install to work.

Are you sure the issue wasn't fixed when you disable all plugins except GP Premium?

Are you using Ads Inserter in your other sites?

Yes I'm sure.

No I use GP Hook.

I try to add my Google Analytics in the hook and dosen't work I'm also redirected to 404 page.

I would recommend checking with your hosting support to see if there is anything in this specific install that's blocking the hook from working.

Since it works in your other installs and my installs, this cannot be a GP issue.

The hook element module is simple - it simply adds the code for you. And in this case, it sounds like your hosting doesn't like some part of the code.

Ok I'll keep looking for where this problem comes from.

Sounds good.
