Based on this:

No type was found that matches the controller named 'FormulateTree'

It sounds like some Formulate DLL's may be missing from your bin folder. Can you explain in detail how you installed Formulate?

Also, please check your bin folder. Ensure that at least formulate.app.dll exists (there should be some others too). That's the DLL that contains the controller indicated by the error message.

Hi Nicholas

I installed it using the Install local option in the Developer section of the backoffice.

I gave the app pool the correct permissions and I unblocked the zip file.

I can confirm that formulate.app.dll is in the folder.

I've attached a screenshot.

Hi Nicholas

I've tried it on v7.4.3 and it works!

One thing I did notice was that I couldn't unblock it. Every time I tried and went back to look, the option was still there. So I downloaded a fresh version of v1.2.13.0 and unblocked that instead.

I will try this fresh version on v7.5.14 and get back to you, but I wonder if related to the pathing in the backoffice apps that Umbraco said they were going to fix.

Thanks

Hmm, not sure what the issue could be then. I'll see if I can reproduce the issue when I get home tonight.

In the meantime, if you could add any more info that you think could help reproduce this, please do (e.g., was this an upgrade or a clean install of Formulate).

Also be sure to check to see if Formulate exists in the applications.config file and the trees.config file in the config folder.

Nope... sorry, but I still get the same error on v7.5.14

I wonder if related to the pathing in the backoffice apps that Umbraco said they were going to fix.

That sounds promising. Do you have any more info about this?

BTW, I happen to have Formulate installed on Umbraco 7.5.13 and it works fine. Perhaps the issue was introduced in 7.5.14 (won't have time until tonight to confirm).

I've also installed Formulate on Umbraco 7.6.x (can't remember the patch version) and it worked fine (though, I think 7.5.14 was actually released after 7.6.0).

Thanks Nicholas,

I might just clear every cache on the server and try again...

I will try to find that article about pathing as well.

Many thanks for all your help.

Hi Nicholas

this of course could be completely irrelevant, but here is the link to that article referring to the change to the pathing in the backoffice.

https://github.com/Shazwazza/UkFest-AngularJS-Demo/blob/master/readme.md

He says:

/app_plugins/umbraco/peopletreee/ contains all the dialogs for the tree "peopletree". notice: this is bound to change as this is a bug. Both editors and dialogs will be in the /backoffice folder.

Thanks

Looks like that page was created 3-4 years ago, so I'm guessing it's not the likely culprit (also, Formulate appears to be using the new path anyway).

Maybe try recycling the app pool. If you have one of the fcnMode values that aggressively ignores file system changes, even a DLL change may not kick in right away.

I just tried this and could not reproduce the issue. Installed Formulate using the "local install" option into a fresh Umbraco 7.5.14 install, and I'm able to click around the Formulate section without issue.

If you ZIP up your entire website (including the database, if there is one that isn't SQL Server CE), I can test that and see how it differs from mine.

You might also want to check the Umbraco logs for any more clues.

Hi Nicholas

the entire site is way too big to zip up.

I was going to zip up as much as necessary but first I thought I'd try a few more things.

I (stupidly, as it turns out) put the .NET compilation onto a separate drive in order to save space on the C drive. I removed this in the web.config, manually removed all the formulate files, removed the temp ASP.Net files, and re-installed Formulate.

And finally, it worked!

Even though it is now working, I still got the error below (which I've chosen to ignore, because the installedPackages.config file was updated correctly):

Server Error in '/' Application.

Glad to hear you got it figured out.

FYI, if you want to see which process is locking the installedPackages.config file, you can use Handle: https://technet.microsoft.com/en-us/sysinternals/handle
