I have a client with an old Joomla 1.5 they dont want to upgrade this year but their host wants to upgrade the server. What is the maximum version of php that Joomla 1.5 will run rather than the min that is listed?
http://www.joomla.org/technical-requirements.html#footnote-1xPHP Joomla! versions 1.5.15 and later are compatible with PHP 5.3.
Would it run ok on 5.3.10? I would guess it would break on 5.4 but I find it hard to build a test machine with old versions to test. So more question from experience.
