Hi,

I am getting the following error when I open the Manage Users screen:

DataTables warning: table id=userList - Ajax error. For more information about this error, please see http://datatables.net/tn/7

[img]ajaxerror1.jpg[/img]
I followed the datatables.net link but I'm none the wiser.

If I OK the alert then the users are not displayed, but I can still use the Select All option and successfully apply actions to the "invisible" users.

Browser debugging indicates a 403 error in user_list_backend.php. From the Network/Headers tab in the debugger:

plus some (valid) JSON containing the user list.

This is a clean install of Piwigo with no active plugins. I have tried uninstalling/reinstalling, but the error remains. Being new to Piwigo and PHP, and not having found this particular error in the forum or documentation, I'm struggling to see what is causing it.

Any help will be gratefully received!

Hello

i'm quite surprised: the server returns a 403 but, when you are logged as admin, you get a result

i'm notifying "my superior" ^^

What does your web browser says in the "response" tab for the Ajax POST request?

HARW · 2018-04-05 11:42:41

Hi

Thanks for responding.

plg, this is the content of the response tab:

Aha! It looks like this issue is down to a ModSecurity rule being applied by my hosting provider. Temporarily disabling ModSecurity through cPanel allows the User List to be displayed. I will raise this with my provider, so hopefully they can amend the rules.

plg · 2018-04-06 10:58:18

Thank you for this feedback. I had no idea why it occured!

flop25 · 2018-04-06 15:44:08

ha I should have remembered this!
It already happened; usually it come from lengthy arguments

Silverman · 2019-06-13 04:00:42

Hi all,

I am also having this issue. Same error message. Same result, unable to see the user list. I have disabled ModSecurity through Cpanel but it has no effect.

Are there any other solutions?

Thanks in advance.

Hi Silverman,

Silverman · 2019-06-14 04:47:48
