After applying the Feb 6th 2018 OES 2015 SP1 Mandatory patch and the latest SLES 11 SP4 patches,

I can't no longer manage iprint manager or printers through iManager. It will be prompted with " Internal error, a page has performed an illegal action" message. I have several servers with iManager and they all had the same issue after the patches. Though I can't manage or create new printer from imanager, Print service behaves normally.

The last time I updated was Jan, 2018.

I have tried to update imanager framework plugin, and update iprint plugin with no help. I have even reinstalled iprint plugin followed this TID

I can't be alone on this issue. Any body ran into or confirmed this bug?
