Steps to reproduce:
- Find a post in the General developer forum.
- Click Reply, so the inline reply box opens.
- Type in 'SELECT *'.
- (Realise it will be better if you can format the SQL using Atto, so ...)
- Click 'Advanced' link.
Expected result: Page loads, and you can continue your post.
Actual result: Allegedly something is wrong with the internet. In reality, I expect something is wrong with the security heursistic config on moodle.org servers.
