Getting 500 errors for non existent pages instead of 404

we finished feature ... we work on performance

Nothing to say about you GREAT job... I'm posting here just to push a relevant (at least for me) question that is bringing my website users to leave immediatly the website itself after getting that error, wasting a lot of working time invested to get better positioning
May be that performance could be better trimmed after a "middle-age, important issue solving" release? :

You have that many non existing pages/links !?

Also what could we do that we do not do, for a free component? while at the same time making a living ?

The problem is caused because J2.5.x made a change that was supposed to happen in J3.0

I took time to find the frontend files that you need to change
Fix was in r1619, the fixes that you need to apply:

code.google.com/p/flexicontent/s ... roller.php

Do this first (category view):
code.google.com/p/flexicontent/s ... tegory.php

Do this first (item view):
code.google.com/p/flexicontent/s ... s/item.php

code.google.com/p/flexicontent/s ... s/tags.php

code.google.com/p/flexicontent/s ... w.html.php

code.google.com/p/flexicontent/s ... w.html.php

At first, a BIG "Thank you" for you help: I'll make the fix today.
But I need to avoid further misunderstanding: I don't like to bore people working so respectably like you do.
I never said you makes nothing for the Community, neither I asked you to loose time for me.
The problem arised from the fact I'm really getting so many errors. I made & daily maintain a website for our own book-publisher activity, also working for free. Starting from the J 1.5 -> J 2.5 upgrade, made 3 weeks ago, I have accumulated more than 3.000 Google links related to 500 errors (yes, really): many pages have different URI due to the different way Joomla & FC works for SEO between versions, and this small bug is a nightmare, in my case.
From a statistical point of view, I have seen that no one receiving a 500 error goes to the home page and looks for the content previously searched in Google: simply leave the site. In my opinion, solving this is more important than having a, lets say, 5% performance increasing in efficiency
And as last thing to say, is there a way to contribute to your work? I'll be glad to help you in someway.

Hello,

you could post an all positive review at JED (i should have added this to my forum signature)

NOTE: to apply the fix scroll down the pages to see the differences marked as red/green

Just to make you aware of: I made the suggested files changes, but results has not changed.

If I go to the already indicated url:
www.mmcedizioni.it/it/catalogo-l ... module=114

I still get the same error:
500 - View not found [name, type, prefix]: catalogolibri-per-generi, html, flexicontentView

...any hint?

Edited:
It seems that Joomla is looking for the 'catalogo-libri-per-generi' part of the URI, that was a directory in FC that now has been renamed to 'catalogo-per-generi', and now the system is unable to find the correct view...
Is that error related to FC or it's a general Joomla related error?

Thanks again for your patience :mrgreen:
