Intermittent error
 

The other day I got a error message when I tried right clicking the > symbol to open the last post in a new tab on a couple of threads. I think I ended up just clicking on the thread to actually read. I just copied the Error - Later I didn't have any problems.

Then today I went to post to the Colorado get-together thread. I clicked on the red reply button, like I usually do, when I received I closed out of that window and opened the thread and tried again to click on the Reply button and got the same thing, went back and tried "Go Advanced" and got the same message. I ended up typing a quick reply and was able to post. I then was able to edit so I could insert some pictures.

I'm using a laptop with Windows 11 and a duckduckgo browser. It is really strange that it is not all the time, fortunately. And I didn't have any problem starting this new thread.
