500 error on Joomla admin login

[DJNickAnnies]

We have some sites hosted with Siteground, and one of these sites has an issue with the admin login. The site in question is http://www.kingstown.uk.com/

When logging in the return simply goes to a 500 error page. I had read the forums and support notes to try and resolve this but nothing is working - folder permissions, changing the admin password via phpMyAdmin etc. It's a corporate site that I need to make urgent changes to but I simply cannot get access. Does anyone have any ideas?

Any help would be greatly appreciated.

Many Thanks

Nick

Quick update. After Siteground did some tweaking the login now just folds back to the blank login, in a loop. So it does not give a 500 error but still won't allow me to login still. Siteground say that because they feel it is not a server error but a software error they can offer no further support, which is just about as unhelpful as you can get - clearly not willing to help, even though they claim to be a good Joomla host. Support is support, not in their eyes I guess...

That URL is displaying fine for me on Brave, Firefox and Palemoon. Is the blank page after the admin login?
If yes that is probably a PHP error. Has the php version been changed recently? You do realise that you are running on Joomla 2.5.19. It is over 7 years old and will have very out of date extensions which can also be the cause.

Hi there,

It only happens when you enter the login details and try to login. I might just rebuild the site if it's on a really old version. Thanks for your help...

We don't usually have a lot to say about websites built with J! 2.5. You can draw your own conclusions from that.

What do you mean if it's a really old version? Where have you been?

I suggest you read General help: HTTP 500 Internal Server Errors. Even though that item relates to J! 3.x, the advice in it is good for any version of Joomla. That's the first step in understanding a few things about your problem.

Apart from these things, good luck.

Haha, sorry, I was one of the original members of the Mambo/Joomla team, but it's been EONs since I have used it, "power in simplicity" very quickly became "confusion in complexity" so I've never used it again. You can find me here in the roster: https://www.joomla.org/about-joomla/hon ... nnies.html

I actually came up with the original Mambo asterisk logo and worked on the icons for the CMS etc...now it just gives me headaches.
