Hi

I'm running 5.0 with quite a few custom (half written) modules - see http://www.runsaturday.com

I'm loving 5.0 - very stable!

However, rarely (one in a few hundred page views?) I'm seeing an error in this deserialize method

I've searched on here and the only links I've found suggest this is AJAX not installed?! That is definitely not the case here!

Has anyone got any ideas how to debug this? Are there any similar bugs already reported

Thanks

Stuart

Sadly I'm still seeing this - and a quick search on here shows that it looks like others are seeing it too on DNN5.01 installations.

When I look at a full stack trace of the problem I can see that the stack includes DotNetNuke.UI.WebControls.SolPartActions and DotNetNuke.UI.WebControls.DNNMenu.OnInit. However, my skin does not use DNNMenu - so I don't understand why SolPartActions is being called?

Any ideas or suggestions about how to debug and resolve this are very welcome!

Stuart

We were getting this problem after upgrading to 5.1 (from 4.9.4). 

After much hair loss I found that gettings users to press CTRL-F5 to reload the page fixed our problem!  For us it must have been something cached on the client browser that was out of sync with the server (perhaps a js file?).

Sounds too simple but I hope it helps.
