 * Hi all have a weird and annoying problem after updating to php 5.4 from 5.2 my
   host 1and1 are moving to php 5.4 they do not support php 5.3 only 5.2 and 5.4
   
   so whats the problem well when I update from 5.2 to 5.4 my wp calendar does not
   work and not got a clue as to why on 1 of my test sites in webmatrix on a fresh
   install with php 5.3 I installed wordpress and wp calendar and it worked fine
   I then upgraded php to 5.4 and it still works fine Great ! so on my mirror test
   site which is identical to the production site I tried to update it from 5.2 
   to 5.4 and again no luck the test site is [pgrac](http://pgrac.stjohn257.co.uk/calendar/)
   there is no calendar showing on the page ??
 * I tried removing the calendar and the database entries completely removing it
   including all custom code from css and functions.php
    I then reinstalled it and
   there is no difference is shows upcoming events in the widget area but still 
   no calendar
 * I am not a programmer and don’t have a clue where to start have tried on other
   forums but don’t even have a clue as to how to start troubleshooting the problem
   apart from the usual disable all other plugins etc
 * Please can someone help solve this problem before I am forced to use php 5.4
