tiburonzzz on "Is Pinboard compatible with PHP 5.4?"

Hi,

I received a message from Bluehost that my account will be automatically upgraded to PHP 5.4 and to test my site will be working after that. I did it (machine2culture.com) and the blog was not functioning properly anymore. Post pages came back with a 404 error.

I wonder if it can be the Pinboard theme I used in wordpress? Is it compatible with PHP 5.4?

Thanks for the help
