Successfully installed Modules showing "Not Found" pages

I installed modules (which shows as sucessfully installed)  but most are showing a "Not Found" page.  Some modules work but most show the "not found" error message.

Does anyone know why this happens and how to fix?

Thank You in advance,

Allen

BTW, I'm using Dolphin 7.0.6

Thx

in admin section /settings try to enable/disable permalinks 

you most likely uploaded the files via ftp, and some ftp programs refuse to overwrite ( . ) dot iteration files. so you need to leave your permalinks on, make sure mod_rewrite is enabled.

then make sure you have the .htaccess file that comes with dolphin uploaded on the server.

your modules that are installed are served with /m/modulename

so the /m is a rewrite from htaccess

if you dont care about SEF URLS then you can disable permalinks, but would do that as a last resort.

Thank You for your help.  DosDawg was correct.  the .htaccess file needs to be the Dolphin default otherwise you'll get "Not Found" pages.

So if anyone experiences the same problem, double check to make sure you're using the original .htaccess file that comes with Dolphin.
