OGP: Caching Message Always Shows

[WillStrohl]

The open graph protocol HTML mark-up cannot be loaded from cache. It is suggested that you clear cache in the control panel to fix this issue.

v1.1 worked but upgraded to DNN 6.2.4 and had issues with profile. Upgraded to v1.3. As soon as you add a new page, you get above error with an ugly black stripe on web page saying Will.S .... End of Log.
Clearing cache, etc. nothing helps. Tried v1.2 same problem.
Event Viewer shows error:
InnerException: Object reference not set to an instance of an object.
FileName:
FileLineNumber: 0
FileColumnNumber: 0
Method: WillStrohl.Modules.OpenGraph.OpenGraphStream.Write
StackTrace:
Message: System.NullReferenceException: Object reference not set to an instance of an object. at WillStrohl.Modules.OpenGraph.OpenGraphWriter.OpenGraphStream.Write(Byte[] buffer, Int32 offset, Int32 count)
Not sure what this means, it actually writes to server, config file changes or creates new one.
The pages from v1.1 did not have big ugly black stripe, only newly added pages. I did not have debug turned on.
Uninstalled module to fix error.

I also get this error - Using dnn7.x

I also get this error, which makes the module unusable.

To help reproduce, here are the OGP settings I use:

Page Title: Home (use Page Settings Title checked)
Page Description: Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. (use Page Settings checked)
Preferred Url: https://dnndev.me/locale/de-at (Use Default Page Url checked)
Site Locale: de-AT
Preferred Thumbnail: File, some jpeg from the site
Site Name: My Dev Site (Use Default Site checked)
Site Type: Websites: Website
Facebook Admin ID(s): (none)
Facebook Application ID: (none)
Enable Debugging: (not checked)

DNN version: 9.13.3

I've put this into my backlog, but I don't know how soon I can get to it. I'm sorry. ☹️

I still have this error:

The open graph protocol HTML mark-up cannot be loaded from cache. It is suggested that you clear cache in the control panel to fix this issue.

Even after clearing the cache or restarting the application pool :-(

Please re-open, thanks!

Hello @MaiklT ... We took another look at this and we're no longer able to reproduce the issue in our test environments. Are you able to provide any more details about how to reproduce this issue?

I installed DNN 9.13.6 from scratch (blank website template, German), uploaded some images and then installed the module 2.1.0. I placed a module on the start page.

In the OGP Settings, I entered:

Page Title: Home (Use Page Settings Title: checked)
Page Description: Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam (Use Page Settings: unchecked, grayed)
Preffered Url: http://xyz.local/ (Use Default Page Url: checked)
Site Locale: de-DE
Preferred Thumbnail: File (a file on your website), selected one of the uploaded images

Site-Level-Settings
Site Name: My Website (Use Default Site: checked)
Site Type: Websites: Website
Facebook Admin ID(s): (empty)
Facebook Application ID: (empty)
Enable Debugging?: (checked)

Worked...

On another portal (where I had installed OGP 2.0.0, uninstalled it - because of the error) and installed OGP 2.1.0 later, I get the error with exactly the same settings as above.
