Our hosting provider, 1and1.com has announced an upgrade to PHP 5.4 effective April 1st. We run two versions of the site:is the live site and is running under PHP 5.2, is a test site running 5.4. While the site itself seems to be OK under PHP 5.4, we are having problems with the some of the administrative pages - both Wordpress and Pagelines pages.
These problems aren't present when switching to another theme - i.e. Coraline. Because of this 1and1 is calling it a "theme problem."
I've built PHP 5.4 from source on my local development server and there are no problems. 1and1.com is not providing PHP 5.4 from the command line, so I can't get a text version of phpinfo() to diff against my build. Nor will they give me access to the Apache error log to see what the errors are. I have enabled debug mode in Wordpress and the only thing I see are calls to deprecated functions in Wordpress. I also have a second site using Pagelines under my 1and1.com account (I have the Developer version of Frameworks) which is not experiencing any problems with PHP 5.4.
Two scrrenshots - one of the Pagelines dashboard204.14KB 10 downloads and one of the Wordpress Appearance => Menus page 462.07KB 11 downloads are attached. The Pagelines debug information is a below.
Are you aware of any issues with Pagelines Framework and PHP 5.4?
