hi,

I have the same problem and found a workaround:

Open the page and wait for about 1 or 2 minutes, now your button event handlers will be called :-S.

Do not ask me why!

If you do not want to wait for a while, you can login as host and select edit mode: the button event handlers will be called.

PS: yes, the module cache time is set to 0.

Hooligannes is exactly right.  I had the same problem where I could not update any text values as a normal user.  However, everything worked when I was logged on as Host.  You MUST change the default cache settings under the instance. 

Go to your module that you are working on

Click on the arrow for the menu options and select Settings

Go to the Page Settings Section

Set Cache Time (secs) to 0

You will want to do the same things under Module Definitions under the Host menu. 

Thank you for posting this, I have spent a TON of time trying to fix this issue.

hooligannes is absolutely right, and thank you very much.

I query this for a while and they tell me and just keep saying: This is a common problem and just set cache to 0.but, as almost a beginner, I just know the Module Definitions can set chche, and I really don't know a module instance can set the cache too. When I saw hooligannes's post and set the module instance's cache, guess what? IT WORKS!

Althougn this is so sample a question, but as DotNetNuke expanding so fast, there're more and more beginners joining, so tell us just the answer, we can extend it well.

Thank hooligannes again.

And I think I can teach other beginner now :)
