What are extensions.cache Error Messages?

General extensions.cache Runtime Errors

extensions.cache file errors often occur during the startup phase of Songbird, but can also occur while the program is running. These types CACHE errors are also known as “runtime errors” because they occur while Songbird is running. Here are some of the most common extensions.cache runtime errors:

• extensions.cache could not be found.
• extensions.cache error.
• extensions.cache failed to load.
• Error loading extensions.cache.
• Failed to register extensions.cache / Cannot register extensions.cache.
• Runtime Error - extensions.cache.
• The file extensions.cache is missing or corrupt.

Most CACHE errors are due to missing or corrupt files. Your extensions.cache file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Songbird), or deleted by a malware infection. Furthermore, extensions.cache file corruption could be caused from a power outage when loading Songbird, system crash while loading or saving extensions.cache, bad sectors on your storage media (usually your primary hard drive), or malware infection. Thus, it’s critical to make sure your anti-virus is kept up-to-date and scanning regularly.
