Any clues in the umbracoLog table?

Sorry for delayed response, finally gone back to this from working on another project.

Just had a look at umbracoLog table and there are alot of data in there. Should it be empty? Should I be looking for something in particular?

Thanks Soren

Look for anything with the word "ucommerce" in it. Also a good trick is to reset the app by running "iisreset", fire up the web page, and immediately take a look at the latest log entries. The interesting stuff will usually come out on top of you order the entries by id.

Back onto this project again - I did find an error

Could not load file or assembly 'Infralution.Licensing, Version=4.7.1.0, Culture=neutral, PublicKeyToken=3e7e8e3744a5c13f' or one of its dependencies. The system cannot find the file specified.

There are whole lot of errors as well in regards to uCommerce editproduct: example here

At /umbraco/js/language.aspx (Referred by: http://www.back2fit.co.nz/umbraco/ucommerce/catalog/editproduct.aspx?id=123&parentcategoryId=75): System.NullReferenceException: Object reference not set to an instance of an object.     at umbraco.js.language.Page_Load(Object sender, EventArgs e)     at System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e)     at umbraco.BasePages.BasePage.OnLoad(EventArgs e)     at System.Web.UI.Control.LoadRecursive()     at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

But I don't think this is license related??

 I have also tried to access our website www.back2fit.co.nz from an external ip and the license file was still not created in root folder.

Results after another app pool recycle

Could not load file or assembly 'Infralution.Licensing, Version=4.7.1.0, Culture=neutral, PublicKeyToken=3e7e8e3744a5c13f' or one of its dependencies. The system cannot find the file specified.

Is the Infralution.Licensing DLL present in the /bin folder? If yes, please check the version number.

Do you have other packages installed on the site?

Hi Soren, here is the list of the packages that are installed for this site

There is NO Infralution licensing dll present in the /bin folder

Could you try reinstalling the latest version of uCommerce, which is 2.5.1.0?

I'm thinking it might be a permission issue on the site. Are there any uCommerce DLLs in the bin folder, e.g. ucommerce.dll, ucommerce.infrastructure.dll, etc.?  

If I reinstall - will I have to create the products again for the store etc?

See the image below of dlls in the bin folder

No. uCommerce will see the existing database and handle any required upgrade required automatically.

I am getting the problem of no XSLT working on my site. For instance, I had navigation working perfectly and now it says

ERROR PARSING XSLT FILE: \XSLT\NAVIGATION.XSLT

All XSLT is broken on the site, including AddToBasket[XSLT].xslt etc.

When I try to save an XSLT file I get this error:

Error occured

System.Exception: Unable to load one or more of the types in assembly 'UCommerce, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. Exceptions were thrown:

Looking at other posts, and trying to find an answer, I believe it must be to do with the license?

I have checked everything else I can find in the forums: the DB string and permissions are correct, all the DLL files are present and correct, etc etc.

Please can you help me find the solution to this? Of course if you need any further information I will be happy to provide it.

Many thanks in advance!

Tim

Seems like you're missing a DLL from your /bin folder for some reason. Specifcally uCommerce can't find "Infralution.Licensing.dll".

You can grab the DLLs from the package and add them back manually.
