Can't log into the Admin console

[Charmie4077]

Really hope someone can help.
I have searched this forum for the answer to this and have not found it.

I am unable to log into the Admin console of my website:
https://www.onlineuserguides.co.uk/admin

I have the latest version of CMSMS 2.2.13
Running PHP 5.6

Screenshot is uploaded

I thought the issue may be the .htaccess file as this was mentioned, here is a copy of what's in my file, sorry for long email.

RewriteEngine On

When you open the developer console (F12) at your login page, you'll see this:
Mixed Content: The page at 'https://www.onlineuserguides.co.uk/admin/login.php' was loaded over HTTPS, but requested an insecure stylesheet 'http://www.onlineuserguides.co.uk/admin/loginstyle.php'. This request has been blocked; the content must be served over HTTPS.

This means the issue is with your https setup and/or how it's being modified in .htaccesss. For a short term fix you could put an htaccess in the /admin directory that forces it to *not* https. Then you can troubleshoot why admin is not working with https (could just need a cache clear, could be something else)
