Hello,
Hoping someone out there can help... noticing these errors in the Front-End server app log several times per day, no consistent pattern though. I opened the NWLOnlineComponents.ascx file in Notepad++ and it seems to be part of Nintex Workflow Live, which we do not have installed as part of our Nintex Workflow 2010 implementation. I would say I'm a novice in the Nintex world, so not sure if this error is a big deal or something that can be ignored if we're not going to be using Nintex Workflow Live. Either way, hoping someone has some information as to what might be causing it, thanks much!
