[Xymon] Unable to Acknowledge Alarms after Update 4.3.26

Hello,

We have dozens of employees that use xymon to monitor various servers around the company. After updating to 4.3.26, no one is able to acknowledge alarms anymore. I was wondering if this was a known issue, or if possibly the update was done incorrectly? Nothing else was modified besides the normal procedure for updating.

Thanks,
