  3. So did you upgrade to WP 3.2? It says it requires PHP 5.2.4 ( ) but 1and1 is still running 5.2.17. Or did you do your trick to run 5.3.99?

  4. Hi!!

    I’m a 1and1 client in Spain, and, at 27 of June 2011, we have currently two options as “PHP Global Version”: PHP5 and PHP dev. I just selected PHP dev and, as far as phpinfo() says, it’s PHP 5.4. That’s really great!!!!

    Greetings from Barcelona!

  5. In my country 5.2.17 > 5.2.4
    So you can already install WP 3.2

  6. Do you think this would allow me to use the auto-upgrade feature of wordpress to bring me up to 3.2.1 from 3.1.4? right now when I try it just stalls at “Downloading wordpress …” and nothing else happens. I already added the .htaccess php 5 code and changed the global settings to php 5, and I have mysql 5 database.

  7. Thank you! that allowed me to update. I didn’t think I had that many plugins that it would cause a problem (4) but I guess it did.

    thanks again!

  8. Thanks for the tip Ryan! I am on Dual Advanced and my phpinfo() reads 5.4 alpha 1 (probably updated since this post). I definitely would not recommend this for a production site since it appears to update from time to time. If only they could get 5.3 installed…sigh….

    I’ve used your trick, and it seemed to work at first. Impress CMS successfully installed, but when the site launched it was full of errors. So if you’re using anything as complicated as ImpressCMS you’re still out of luck.

    I really wish 1and1 would hurry up on this one, ImpressCMS could make my life so much easier!

  10. Dude, thanks for your great post! I really needed 5.3 to use DateTime::diff() and now everything is working fine.

  11. It worked like a charm. Thanks a lot for this trick!
