Product installs, backs up and restores flawlessly.

When I try to add or edit a user in the backend it gives me a File not found error consistently on every installation, whether with SSL or not. Not sure if it's a bug or a server misconfiguration.

Backup log attached for completeness. Thanks

Error log lines from CPanel:

Great Product!

Hello Keith,

I think that the issue is caused by your host.
When editing a user we pass a token to double check if the request it's a valid one.
This token is a long, random hexadecimal string, I suspect that your hosting has some rules set inside the mod_security2 Apache module that see such string as an attack and block the page.

Since there isn't a specialized page for the error 403, your server fallbacks to the standard 404 error, file not found.

I'd suggest you to contact your host, they can simply tweak their rules and prevent this error from happening.

Thank you Davide.

It must be the case because I installed it on a different shared host running Apache and it works fine.

I will try to solve it with my hosting provider. Is there any more specific technical data that I can provide to them to help modify the server settings?

No, I already gave all the required details.
I can only add that the token string is something like this:
db0b2b184335853bd25b1627eec0b8c994a2dcc3540bf48a4509ef0cdc0b08d76f628e9980976d5f92faf9741212ca69581d9b4263b2095e6836803b958a8bc1

But your host can see that looking at the logs.

It appears that PHP 5.4 is the problem on my server. Selecting 5.5 or 5.3 solves the problem.

Support at my hosting company didn't think it was a mod_security issue. but for whatever reason, switching to 5.5 fixed the problem without breaking my sites. I'm a happy camper.

Well, that's good news!
Can you please tell me the exact version of php 5.4? I'd wish to run some tests and to exclude possible bugs.
