Admin login form is missing

Grindlay

Randomly, my admin login form has gone missing:
https://support.lunaria.co.uk/scp/login.php
Server MariaDB 10.3, PHP 7.3, Apache 2.4
Nothing in the error logs.
I tried upgrading from 1.14.2 to 1.14.3 - deleted ost-config.php and started again but problem persists.
Any ideas what to try next?

My guess would be that you have an .htaccess or something redirecting the traffic away from the login.

thanks for the reply. There is no .htaccess file in /scp
The .htaccess in the root just has:

#php -- BEGIN cPanel-generated handler, do not edit
# Set the “ea-php73” package as the default “PHP” programming language.
<IfModule mime_module>
  AddHandler application/x-httpd-ea-php73 .php .php7 .phtml
</IfModule>
# php -- END cPanel-generated handler, do not edit

i.e. the cPanel PHP handler
As you can see from the link, the login form code is just missing.
I may try to delete the whole installation and start again from scratch as it looks like something has gone missing.

After a lot of head-scratching, I finally found the cause of this behaviour. The problem persisted even after a complete re-install of OSTicket including DB files. This suggested it was my hosting setup rather than OSTicket.
I installed on https://www.mydomain.com/support which also had a subdomain created https://support.mydomain.com
The main domain mydomain.com had a wordpress install. As we know, wordpress is very aggressive with its .htaccess rules, taking any URLs with /support and re-writing them to a 404, or depending on your setup, re-directing to index.php. In my case, all requests for /login.php were being redirected to /index.php so the login page was never appearing.
The solution was to create new rules in the .htaccess file in the root of my site, placing them before the Wordpress rules:

#Rules for /support sub folder
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} ^/support/(.*)$ [OR]
RewriteRule ^.*$ - [L]
</IfModule>
#end

Next, I created a .htaccess file in the /support folder like so:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /support/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L]
</IfModule>

My next problem was that when I followed the login link, I got a 422 error. I have no idea why OSTicket generates this, but the code in login.php is:

// Browsers shouldn't suggest saving that username/password
// Http::response(422);

I just commented out the second line, as others have suggested on this forum.
I now have a working OSTicket install.

We return that response code because (as the comment says) Browsers shouldn't suggest saving that username/password. Maybe your environment handles 402 codes differently than most webservers? On vanilla instances and heavily modified instances of Apache/NGINX I've never run into this issue.

Cheers.
