I noticed that Moher was misspelled twice in a post, which could make searches a nuisance, so I attempted to correct the two instances, however, I received this message:
Oops! Your edit couldn't be submitted because:

The post is fine, any other changes would be tampering for the sake of it.
Place names are particularly important in a Travel forum, I reckon, so it should be possible to make such changes.
