Hello,

I have a problem in my Dashboard.aspx page:
After moving between my theme and the default theme (through the page properties in admin) suddently the Dashboard page crashed displaying an error message (see attachment).
The problem is identified to the events.ascx module and the corresponding web part (when trying to add it dynamically instead of hardcoding it. When I remove it from my page, everything works fine. Therefore, I noticed that the problem with this web part keeps on on any page I try to insert it.

I have to say that I replaced my theme's templates folder (App_Templates/myproject/) with the new one from the Default folder (because I had recently updated the monoX to the recent version). Might this replace  have caused the problem?
(being more specific: I have a folder "Myproject" in App_Templates that was a copy of the Default templates folder. Lately I moved to an upgrated monoX and while trying to restyle Dashboard page I copied the new version's Default template folder to "Myproject" template folder. )

Also not to forget to say that when trying to change the Dashboard page's theme and Master It wouldn't allow me to do so:
"The master page and/or theme you entered are not compatible with the selected page."

This was the beggining of the problem...

I found a possible workaround that still has some issues though. Please see here if interested:

Hello again. I am really sorry but I figured out that this might have been some short of server cache problem as I changed many properties back & forth throughthe admin.

I am not experienced at all in working on a server (especially with .NET projects) and I couldn;t figure out th eproblem easily.

Finally, I changed my web.config file in order that the application would recycle and voila! everything worked.

I don;t know wether there is a general issue with the MonoX admin panel and cache as it often throughs me messages like this "The master page and/or theme you entered are not compatible with the selected page." 

Thank you,
Panos

Hi Sonap, it's good to hear that it started working again.

One note - while logged in with a user that is in "Administrators" role, you will have the admin panel at the top all the time. Because of that panel, everything in the body is in an update panel which might cause strange behavior. So, you should test everything with users that are not in "Administrators" role just to make sure everything works well that way.
