Can not open the extension manager

[qzhang]

I import an extension into TW, and I want to delete that, but I can not access to manage list as follows.

And I tried to delete from extension fold, then  restarted the server, but still can not import new one.

I have no idea how to delete the extensions clearly.

Hi qiqiang Zhang​,

What is the ThingWorx version? Database type? OS? tomcat version?

Is it a newly installed version or upgraded from previous version.

If it was upgraded; was the upgrade process of export and then import to new version was followed?

If you are not able to view the Extension Manager Page; it is probably because their is some error in some extension.

You can try following to resolve this issue (Only if it's not a Production instance).

Take an export of all entities and data. In a fresh install of ThingWorx; import all the extensions that existed in the previous version. Then import the entities and the Data.

I just upgraded tw from 7.2 to 7.4 , progress in unbantu, tomcat is 8.0.33,

and I can access to by [server address]/Thingworx/Runtime/index.html#master=ThingWorxMonitor&mashup=ExtensionManagerListing but not the manage icon。

It's a bug of TWX 7.4 apparently. On the previous version, the link of Extension Manager is

[server address]/Thingworx/Runtime/index.html#master=ThingWorxMonitor&mashup=ExtensionManagerListing

Hi Quang-Dung Ngo​,

[server address]/Thingworx/Mashups/ExtensionManagerListing

should actually redirect to

[server address]/Thingworx/Runtime/index.html#master=ThingWorxMonitor&mashup=ExtensionManagerListing

automatically.

[qzhang]

But it does not

Hi Ankit, normally yes. But it's not the case on TWX 7.4

Hi Quang-Dung Ngo​,

I have ThingWorx 7.4.0 on my local instance and it works fine for me. I get redirected to [server address]/Thingworx/Runtime/index.html#master=ThingWorxMonitor&mashup=ExtensionManagerListing on opeing the Extension Manager page.

Maybe some setting changed on your instance after the Entity/Data import.

So, does all the redirection (Mashup to Runtime) not working for you in ThingWorx 7.4

Did you check the extension manager before importing Extensions and entities/Data?

[qngo]

The Extension Manager worked fine before updating to 7.4. Here are the errors on TWX 7.4 when I open the Extension Manager from the menu.

There are also other errors that I only see on TWX 7.4 after updating:

I already opened a support case for all these errors (and other ones). I'm still waiting for answer.

[server address]/Thingworx/Mashups/ExtensionManagerListing

to

[server address]/Thingworx/Runtime/index.html#master=ThingWorxMonitor&mashup=ExtensionManagerListing
