In this example sentence, the semi-colon is inappropriate because what comes after the semi-colon is only a phrase rather than an independent clause.
In my opinion no punctuation is required, but I am not sure whether a comma can replace the semi-colon or otherwise. Could you please fix this problem?
Many thanks for your valuable contribution. However, I am wondering whether the moderators are going to change this example sentence in the database so that the error would not appear in the future. At any rate, I hope the empowered individuals concerned will make the necessary corrections and update this example sentence as soon as possible.
