Editing, creating and duplicating items failure

[Gronneunger.dk]

I don't remember when it started.

At first it was just accationally.

Then it became more and more often, and now it's every dam'n time.

No matter what I do - creating a new item, duplicating an item, editing an existing item - I get an error or I'm thrown back to the full list of items.

Sometimes the action acutally goes through anyway. Sometimes it doesn't.

When I try to duplicate, I get a "http error 500" blank page as a result (but the item has duplicated).
When I try to edit amounts of an existing item, I get this in a little red, temporary popup:

function (){if(h){var d=h.length;!function f({n.each(b,function(b,c){var d=n.type(c);"function"===d?a.unique&&k.has(c)||h.push(c):c&&c.length&&"string"!==d&&f(c)})}(arguments),b?e=h.length:c&&(g=d,j(c))}return this}

When I try to create a new item, and choose to "Save and stay" after filling out the first tab, I end up on the blank "http error 500".

I've tried to google so many times.
But none of the possible solutions I've found, have had any effect.

I've tried to edit "php_value max_input_vars" through .htacces.
I've tried to remove lines from this file: /adminXXXX/themes/default/template/controllers/products/helpers/form/form.tpl

Nothing!

I've run out of ideas. But I would really like my shop to be up and running again. Like, wouldn't it be lovely to be able to add new products?

Can anybody help me with this? Give me a hint? Anything!!

(I'm running PS 1.6.0.8)

The possibilities are endless. Have you tried looking at log files and see what's generating the 500 error?

 

Also have you tried to update your PS to v1.6.1.17 the latest 1.6 version?

 

Another solution is to do a clean install on a separate folder and see if the error persists. Maybe it's from your php configuration, maybe it's a module

Oh boy, that was NOT what I wanted to hear!   

 

I guess, the easiest way to go around it, is to do a clean install. *sigh* Otherwise I'll probably never find the source of the problem - I have so many hacks, edits, modules and customizations I wouldn't know where to begin.

 

Well, thanks - even though I was hoping for something more like "just push the big red button, and everything will be alright!"
