This bug is at least two distinct issue:

1. Refresh rate is set to never.

This value is not handled correctly, because ajax is used.

2. Ajax reloading does not work as expected

For the first issue, I've the following patch:

If I add following blocks on my horde-alpha portal:
- Horde_Block_Fortune
- IMP_Block_Summay
- Horde_Block_Weatherdotcom

The corresponding block contains following message:
/*-secure-{"response":"Horde is not activated."}*/

This message is loaded on the block with following Ajax query:
http://<server 
address>/services/ajax.php/horde/blockAutoUpdate?blockid=Horde_Block_Fortune

My debug log is below:
