Hi,
My DNN 4.4.1 website has experienced several recurring errors that I have been unable to track down a cause for and I really need someone's help with this as I cannot edit in many of the modules on the site. Also, in the recent past I was unable to add a module to a page as well. My hosting provider, iHostASP, has moved the site to a new server and for a while it worked fine but now it is exhibiting the same problems as before.
An abbreviated summary of the errors are as follows:
- Object reference not set to an instance of an object. ---> System.NullReferenceException
- Conversion from string "" to type 'Integer' is not valid

This error occurs in the Media Module error after editing an image name or any other change:
Error: Edit Media is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.UI.UserControls.UrlControl.get_UrlType() at DotNetNuke.Modules.Media.EditMedia.cmdUpdate_Click(Object sender, EventArgs e) --- End of inner exception stack trace ---

XMOD4 Error loading form for editing (my message-not a part of message below)
A critical error has occurred.
Conversion from string "" to type 'Integer' is not valid.

Host Settings Error
Error: Host Settings is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Modules.Admin.Host.HostSettingsModule.cmdUpdate_Click(Object sender, EventArgs e) --- End of inner exception stack trace ---
These are just three examples of what I have seen throughout the website in various modules leading me to believe that the DNN installation must be corrupted. If it is, how would I fix it? I can supply more verbose stack traces if needed. Thanks!
