I’m getting this error a lot when I create a thread, especially if I’m uploading pictures. If you don’t reload the page it will sometimes just reload on it’s own while you’re editing. Using Safari.
I’ve had that problem happen often a while ago. I haven’t had that problem recently, but I just pressed ignored, copied all of the text (in case it didn’t save, I think it always saved but I didn’t want to lose anything), and tried again. I think that was all it took. But, it would be nice if there was a fix for it.
Like the other Riley, I also copy all the text and press ignore.
Unfortunately this is a Discourse (the forum software) bug and not something we can fix ourselves until they release a new update… But yeah, this can be annoying.
One thing you can do to reduce this is to be sure that you have closed any old tabs you may have open for the MRC.
