• DNN Version Number - 4.4.1
• Links module Version Number - 3.3.0 
• Trust level (most shared installs will be Medium Trust)  - Medium trust
• Steps to reproduce the issue

I created a new module of links and set it to dropdown.
Each link in the dropdown links to another page in the website and opens in the same page.
This process doesn't work(same page reloads) if the user is not logged in but works for logged in users.
The same work if the link list is not in dropdown mode. So not an issue of permission.

DNN settings - compression - off
whitespace filter - off
cache - moderate
friendly urls - off

Kindly let me know if this is an existing problem and is there any resolution?
Many thanks in advance.

thanks for the reply, but I am still struggling to find a solution for the above.

I switched off the caching but the dropdown still doesn't work if the user is not logged in.

My host settings are -

Performance Setting: Select how to optimize performance.	No caching
Authenticated Cacheability: Sets the Cache-Control HTTP header value for authenticated users.	NoCache Private Public Server ServerAndNoCache ServerAndPrivate
Compression Setting: Select the type of Http Compression to use.	No Compression Deflate Compression GZip Compression
Compression Level (Deflate): Select the level of compression to use for the Deflate Algorithm (this is ignored if the GZip algorith is selected)	None 1 2 3 4 5 6 7 8 9
Use Whitespace Filter: Select this to remove excess white space from the response sent to the client - this will result in a smaller download (10-15%) but it will make the html less readable.
