mojoPortal Version 2.3.5.1 MSSQL
Operating System Microsoft Windows NT 5.2.3790 Service Pack 2
ASP.NET Version v2.0.50727 Running in Full Trust

Joe it was the permissions on the file.

It works!

May I recommend a new forum topic. (The idiots section of simple oversights).

For example loading the files to IIS to make flicker work, checking permissions on a file when adding add-ons. My favorite. Different folders for asp3.5 vs 4.0 (smile)

Either way, your support is great and MojoPortal is second to none.

I hope you can look to us for a list of add-ons and product requests to further your product offerings from the none programmer universe.

Exactly i get this error information:

Hi, I search my folder and there is not such file that i delete it. I think it is better i reinstall mojoportal because i worked on portal a little.

However thanks for your helps.
