A few of our customers have found that after installing the Tealium plugin for Magento and trying to go to its related configuration page they will come across a "404 Error Page not found." This tutorial covers some solutions to resolve the issue.
There are a few things to try when you get this error. They are, in order of severity:
Log out, then log back in
Flush the Magento cache
Reset the Administrator roles
The first is self explanatory. Simply log out of the Magento admin area, then log back in. This should reset some of the Magento cache and hopefully allow access the config page.
If this does not work, try completely flushing the Magento Cache.
Go to System -> Cache Management
Click the Flush Magento Cache button.
Then log out, and log back in.
Try accessing the configuration page.
If you still get a 404 Error, the next step is to manually Reset the Administrator Roles.
Go to System -> Permissions -> Roles
Now click on the Administrators role in the list. There may only be one item listed, or maybe more.
Click the Role Users item on the left, then the Reset Filter button on the right. Lastly click the Save Role button at the top right.
Now go through the process of Flushing the Magento cache, and again log out and log back in.
One of these techniques should fix the problem. If you are still experiencing 404 Errors after trying all of these solutions, get in contact with us and we will help you as best we can.
