Today I find that when I change a post code tags from
[code]
blabla
[/code]
to this [code=cplusplus] blabla
[/code]
It doesn't work and acts as if something were misspelled or code tags were not present. But when I erase the [code] and retype the whole thing it works ok. Are there some hidden characters in that line causing the problem? I've had that problem 3 or 4 times this evening.
