This question perturbed me as it doesn't seem to have a clear home. I bugged mSObugged mSO about it, and they say it doesn't belong there. There was a suggestion for SF, which it patently does not fit, and another for Pro Webmasters, which sounds iffy at best.
There is a slight quality issue, which contributes to the problem. There is no cut and dry question, but that's probably because it's hard to tell where the problem lies. I have little knowledge of any of the topics discussed there, but on the surface I couldn't tell you if this is a problem with PHP or the CentOS box itself. Can it be solved using phpMyAdmin?
I think this question well demonstrates the problems with overlap among sites, and how even high reputation users might have no idea what's on topic for other sites. There weren't any high rep people who VTC'd this question, so it may just be a fluke, but it's interesting to me still how nobody can tell where this question should go.
In my opinion, this question 100% belongs here, and if it doesn't then I want it to belong here!
I think we should be a little more open about questions that drift towards simple server administration and light development, as most Super Users around here seem to do both quite often. There are some very fine-nay, invisible-lines drawn around the matter, and I for one would like to see the SU community broaden its scope just a tad to better cover the overlap.
