Is there a limit on how much code you can include when using the code insert option

Hi BigG 

Could you try inserting the same code here as a reply?

We can then determine if there's a problem inserting code into a RoadTest Review versus in other content types.

Hi cstanton 

I tried but it did not work. I can copy code into the widget but when you click the OK button nothing happens.

This seem to be the limit. If I add more lines of code then it will not update.

Testing code insert.

Hi BigG ,

Could you try a different web browser? What are you currently using?

I was able to insert the code using Microsoft Edge.

That is strange. I tried both Google Chrome and Mozilla Firefox and neither worked. Maybe it is a LinuxOS issue. Who knows.

Thanks BigG ,

I've raised this with the development team to attempt to reproduce, I have not been able to reproduce this on the Community or in our non-customised instance of the site, so it will go through our tester first, and then to the dev' team to investigate as it may be a problem we've accidentally introduced.

Thanks for your patience, and I may come back to you asking for more information.

Thanks cstanton for the update. Much appreciated.
