We're sorry, an internal error occurred that prevents the request to complete.

Dear all,
I can see many topics concerning this issue and i am not sure if anyone has solved this matter yet. Its becoming really annoying for a customer of mine and I have really tried everything with no luck though up till now, please help me on this to understand the real nature of problem and hopefully to solve it.

version using 2.4 nopcommerse with SQL server 2008
web host framework: Microsoft ASP.NET support (Version  4.0.30319.1)

At first i had a problem with the initial installation online with the nop db because it was published in the web host sql server before start the web installation so after many tries in the installation of the deployable site i removed the db from the host and choose restart installation and create db if not exist with full success.

The site now is up and running (http://fashioned.gr) but now i have a major issue regarding any new or old product. When I try to add a new product it works fine and I put all its attributes, category etc. but then the product when i try to view it in the public store or even preview it returns me the following error:
'We're sorry, an internal error occurred that prevents the request to complete.

Our supporting staff has been notified with this error and will address this issue shortly. We profusely apologize for the inconvenience and for any damage this may cause. You might want to try the same action at later time.'

of course this error is what the error page shows and not the real issue. From the search in the forums i realized this should be an issue with the Microsoft framework v4.0.30319. I added the solution you have proposed in other topics in my web.config but the error remains.
'<appSettings>
    <add key="aspnet:MaxHttpCollectionKeys" value="2000" />
</appSettings>'

Thank you in advance for your help and support since i am using you solutions since version 1.7 and i am more than happy on what you provide for all of us.

I presume that your exchange rate and primary currencies are not configured

A.M. you totally saved my day with your fast reply. i thought it would be something easy but i could not see it clearly. thank you very very much for point it out.

Now i have the same issue for the 'My Account' and for the 'Blog' but now i am suspected of what it might be the error.

Great support and extremely fast reply.

Please provide the full error stack

I am receiving this msg whenever i click the Clear Log button in Administration/Logs

It's just the generic "something went wrong" message.  You'll need to find the actual error in the log to determine what is wrong.

Yes indeed, generic error msg...
Well, the problem is, through a mistake, i managed to get 450.000 warnings. They're the only thing in the Log, but i don't feel like deleting them 15 by 15... the Clear Log returns the error.
Maybe i should try looking into sql database to get rid of those...

Just log into your DB and execute query:
TRUNCATE TABLE "nop_log"

after that you can clear from NOP
i have to do this regularly, wish i could automate it to be done every so often
