Troubleshoot CMS Files


Typical CMS Opening Challenges

Safari Isn't There

When trying to open your CMS file, you get the error "Can't Open CMS File Type". Usually, this is because you do not have Safari for %%os%% installed. The typical path of opening your CMS with a double-click won't work because %%os%% cannot make the program connection.


Tip: If you have another software that you know opens CMS files, you can select it by hitting the "Show Apps" button.


Incorrect Safari Version

Sometimes your installed version of Safari won't support your Content Management System Web Page File file. You will need to download a newer version of Safari if you don't have the right version. Your Content Management System Web Page File file was probably created by a newer release of Safari than what's currently installed your computer.


Tip: Right-clicking on your CMS, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.


Summary: Not having the right Safari version on your computer can cause problems opening CMS files.


Other CMS File Issues

In the majority of cases, installing the right version of Safari will resolve your issue. There can be external issues inside of %%os%% that are causing these errors when opening CMSs. These other problems include (listed in order from most to least common):

  • File references in the Windows Registry for CMS are wrong
  • Mistaken removal of the Windows registry CMS description
  • Incomplete or bad installation of a software application associated with the CMS format
  • Your CMS file is corrupted (issues with your Content Management System Web Page File file itself)
  • Your CMS has adversely impacted by malware
  • CMS-related hardware has device drivers that obsolete
  • Windows has inadequate resources to open your Content Management System Web Page File file
