I have several clients on bluehost. Most work fine but one, who is on box290 has a severe problem. The site is often down, no PHP working anymore, error message "SHTML Wrapper - 500 Server Error". Customer service says it's a coding problem but this happens at a point where there was no update for weeks and even a standard WordPress blog (installed via fantastico, no manual changes whatsoever) wouldn't work anymore.
I googled it and it seems to be a common problem with bluehost. However, some people report it became better once bluehost moved them over to a new box.
My question: how is this possible? Can I just ask them to do it now or do we need to wait until the site is down again for a couple of hours?
Any help greatly appreciated! Thanks.
