This is fixed in Date_Holidays 0.21.0 which will be included with the 
next release.

How a fix introduces a problem:



function_exists needs a string argument, this is corrected in 1.2.1 and

immediately breaks the 1.2.1 version:



the easter_days function returns the number of days after Mar 21 
instead of a Date object,

and calling a member function of an integer is not possible.





With my poor PHP knowledge it should be moreorless:



  396     function calcEaster($year)

  397     {

  398         if (function_exists('easter_days')) {

  399             $mar21offset= easter_days($year);

  400             $eastern=new Date(sprintf("%04d-03-21",$year));

  401             $eastern->addSeconds($mar21offset*86400);

  402             return($eastern);

  403         }





Kind Regards,

This has nothing to do with the error message of this bug report. 
Beside that, this patch is already applied in 1.2.1:

http://cvs.horde.org/co.php/groupware/patches/Attic/pear-Date-Holidays-Driver-Christian.php.patch?sa=1&r=1.2

That cause the problem:



diff Date/Holidays/Driver/Christian.php Date-new/Holidays/Driver/Christian.php

398c398

<         if (function_exists(easter_days())) {

---

See message below.

Replacing the pear/Date folder by the pear/Date folder from

the 1.2 webmail edition brings back life in the program,

so I can go on with further testing, hoping that this does not break

other things....



Good luck with your nice program!

Dear Developers,



I understand that it's frustrating if your result of hours of coding 
breaks due to third-party software,

but what I see is that 1.2 works very nice and 1.2.1 simply does not 
start properly because of

the Dutch variant of this error message: Menu at the left and blank 
screen, no portal, so I've to

stick to 1.2. Is there, apart from switching off holiday display, a 
workaround, e.g. copying

the 1.2 version of the pear/holiday package into 1.2.1???



Thanks a lot and kind Regards,

Please stop reporting duplicate bugs in software that isn't ours.



Can we just get rid of Date_Holidays support?
