500 internal error admin panel login

[pogodno_69]

Hi,

 

I can't login to admin panel Presta 1.5.6.2., I've got an error: "500 Internal Error
The server encountered an internal error and could not complete your request".

 

I've cleaned cookies, it looks the same on many browsers.

 

I've turn on debug mode.

 

Front-office works, I can login.

 

There are some errors on one page checkout. When I'm trying to login as on old client, there is an information (under the order address:

 

Notice: Undefined index: HOOK_SHOPPING_CART in /cache/smarty/compile/d8/54/d3/d854d3486c6de64e041d6073b69b9ddea5c262e0.file.order-address.tpl.php on line 300

Notice: Trying to get property of non-object in /cache/smarty/compile/d8/54/d3/d854d3486c6de64e041d6073b69b9ddea5c262e0.file.order-address.tpl.php on line 300

 

It's still possible to make an order.

 

Last log:

We've got Page Cache module. Last days it was turn off and on few times. There is also a cron job, but not used at the moment.

 

Last thing I was doing in admin panel was watching list of orders and statistics of sales (normal Presta module).

 

Thanks for you help

Hi there,

 

I'm having a 500 Internal Server Error whenever I try and log into Admin Panel.

The main website appears fine.

Any ideas what has caused this, and what folders or files to check?

I'm using version 1.6.0.14

was working about 3 weeks ago when last updated website.

Thanks for info. I had seen this link earlier today and tried to follow the steps to no avail.

I had managed to set Error logging but I do not get any error codes.

 

Why has the admin folder randomly stop working? Is this normal?

 

There is no guideline on what folders need to be set at specific permissions and cannot find the htaccess file  folder.

 

Feel really frustrated on how this taken all day to fix and can't.

Really could do with someone to talk to, as all these threads mean nothing to me as they don't have paths to the files specified.
