Apparently, it was because I didn't have PHP 5. OK. So. I haven't changed the installation; I haven't changed any options; I haven't updated anything. But all of a sudden my website decides it doesn't have PHP 5 and gives me a 500 error? The illogic of it escapes the slow-speaking, not-listening support person. She refuses to pass me on to a supervisor until I say I'm going to tweet about this if you don't. Wow, instant response. But, uh, no wait. I hear this disembodied male voice for awhile. And then support person comes on and says supervisor is at lunch. Why do I not believe her? I'm boiling mad at this point and hang up before I blow a geyser. Bad me.
I noodle my brain, search the web, and remember that I just have to replace a file with an old copy. It works. The really weird thing was that while I couldn't see my site on my computer, I could on my iPod Touch.
I wrote this post because 1and1.com sent me an e-mail saying:
Thank you for contacting us.I replied:
Regarding the conversation that we had, please be advised to use php version 5. You can refer to the link below:
If you still have any issue, please let us know.
If you have any further questions please do not hesitate to contact us.
Please be advised that this is a well-known problem with 1and1.com and not just with WordPress (do a search and you'll see). For whatever reason the .htaccess rewrites itself and needs to be set back to include the line:I'm starting to think that instead of paying 1and1.com for a site that works most of the time but with poor customer service when it completely, suddenly craps out, I should pay for something like Squarespace.
AddType x-mapp-php5 .php
My other website, using the exact same WordPress installation, using the exact same PHP, had no problems at the same time as my main website spontaneously had the 500 error. Stop blaming your customers for a problem at your end. I will be looking for alternatives as this is a recurring issue that I have then have to remember how to resolve myself because only once have you guys been able to do it. I have also tweeted on this. I expect the usual nothing from you guys.
