After adding some entries to my Dictionairy for a Document Type I made, I changed the language of Administrator back to English and all my Document Types suddenly disappeared!
Strangly enough I can still watch the Content entries, except for the Document Type I added the Dictionairy items for, it throws the following exception (Browsing to Administrator throws the same exception):<span></span><span style="font-family: Arial, Helvetica, Geneva, SunSans-Regular, sans-serif;">Exception Details: System.ArgumentNullException: Value cannot be null. Parameter name: value
Also try deleting the umbraco.config file to clear any cache and change or touch the web.config file to restart things and recreate the umbraco.config file.
I did see your reply, although I wasn't sure I fully understood it. Restarting the application didn't work and I do not have any umbraco.config file in my Umbraco installation.
Just to inform: I just installed a completely clean Umbraco installation which I attached to the Database of the one that didn't work. I get the exact same exceptions, so I'm pretty sure it's a database problem.
I have decided to set up a new package and see what data I can still import. It's mostly the Document Types I am worried about. I was planning to make it a package after the translations were done, so hopefully everything is still in the database.
Anywho, I do think some of the Umbraco developers should look into this. I won't make it a bug on codeplex as I have no idea how I caused it (I don't think just changing the language did). I think it's pretty serious that a whole Umbraco installation will just crash on someone while doing such minimal changes.
But I finally found what caused all my troubles. Apperantly there is a bug in Umbraco that makes it crash on you when you create a Document Type and have it's name start with #.
I had the same problem, that I got this error, when trying to enter the Content section. Then I went to the documents as suggested in this post. I saw, that each document could not enter the masterpages folder. I added the aspnet user to the security settings. After having done these settings, there were some errors in my masterpages, solved them and then I could see my document settings and the Content pages. Everything works fine.
Hope this will help someone who is facing the same problem.
Document Types Deleted
Hello,
After adding some entries to my Dictionairy for a Document Type I made, I changed the language of Administrator back to English and all my Document Types suddenly disappeared!
Strangly enough I can still watch the Content entries, except for the Document Type I added the Dictionairy items for, it throws the following exception (Browsing to Administrator throws the same exception):<span></span><span style="font-family: Arial, Helvetica, Geneva, SunSans-Regular, sans-serif;">Exception Details: System.ArgumentNullException: Value cannot be null.
Parameter name: value
Have you tried recycling the application pool?
Also try deleting the umbraco.config file to clear any cache and change or touch the web.config file to restart things and recreate the umbraco.config file.
I did now, without succes. Thanks though.
I posted another option a second before you and wanted to make sure you saw it.
I did see your reply, although I wasn't sure I fully understood it. Restarting the application didn't work and I do not have any umbraco.config file in my Umbraco installation.
Thanks
The file should be under the /data folder off the root. It's where umbraco stores a working cached version of your content nodes.
The cache was recreated, but didn't solve the issue.
Just to inform: I just installed a completely clean Umbraco installation which I attached to the Database of the one that didn't work. I get the exact same exceptions, so I'm pretty sure it's a database problem.
Spamming my own thread here...

Again sorry for the spamming!

Please create a new work item in Codeplex, add scenario to repro and you'll get my vote ;)
TIA,
/Dirk
I did: http://umbraco.codeplex.com/WorkItem/View.aspx?WorkItemId=23494
I can reproduce it by simply making a Document Item like #ContactForm, I forgot to add I'm using the 3.5 config, but I don't think that's a problem.
Hi there,
I had the same problem, that I got this error, when trying to enter the Content section. Then I went to the documents as suggested in this post. I saw, that each document could not enter the masterpages folder. I added the aspnet user to the security settings. After having done these settings, there were some errors in my masterpages, solved them and then I could see my document settings and the Content pages. Everything works fine.
Hope this will help someone who is facing the same problem.
