[horde] Horde_Core-2.4.2

[Nuno Carrilho]

Hello, 

I've upgraded Horde_Core-2.4.1 to 2.4.2 and I got the following problem: 
The webmai page does not open and I have the following PHP error: 

PHP Fatal error:  Allowed memory size of 262144000 bytes exhausted (tried to
allocate 23616 bytes) in /.../config/conf.php on line 0, referer:
<https://xxx/admin/config/> https://xxx/admin/config/ 

I've downgraded and It's OK again. Every other packages are upgraded ... 

Can someone help? 

Best regards, 
Nuno Carrilho
