I just posted this question:
It was quickly closed as off-topic because "recovering from hacks" is listed in the FAQ as something that shouldn't be posted here. However, that prohibition is listed under the sub-heading "[do not post things] that require professional hands-on involvement".
If recovering from this hack required professional hands-on involvement, I certainly would have avoided asking it, and instead sought professional hands-on involvement. However, I really don't see how this is a case where professional hands-on involvement is required. I'm just looking for a way to edit the .htaccess file. What if I had re-phrased the question, just asking for this without mentioning that it was for the purpose was to recover from a hack? That seems like the same question to me, except with less back story.
