"Invalid HTML" errors on posting a message.

[SRobertJames]

I'm trying to post a question but keep getting the following error:

"Correct the highlighted errors and try again."

"Your post has been changed because invalid HTML was found in the message body. The invalid HTML has been removed. Please review the message and submit the message when you are satisfied."

There is no HTML in the message and no other highlights that I see. But when I click "Post", i get the same message over and over.  I've tried deleting the code I pasted in, but still get the same problem.

Hi @SRobertJames, 

Welcome to the ST Community and thanks for reporting this. Could you please share the content you are trying to post? I will have it investigated.

Should probably log from an ST scripting side.

See the error occasionally, and is transitory, push to post again, and it does.

If you've watched the scripting from the editor sometimes you see it render the post in HTML codes, and then it resolves into more classic form.

Generally it is just text typed in, no particular formatting of post or special features.

Failed with this error when I edited, and pasted in the memcpy() line.  https://community.st.com/t5/stm32-mcus-embedded-software/uart-dma-multiple-transmissions-receptions-failure/td-p/606833

Pulled the formatting, which I didn't care for, but upon first submission gave the HTML error, clicked Post again and it succeeded.

ie I did a cut-n-paste from a Code Box in a prior message. Basically a single line, but the Code Box formatting followed the line.
