When manually upgrading Joomla through the extensions manager, I get the following error:
Installation unexpectedly terminated:Refresh Manifest Cache failed: Extension is not currently installed.
I was upgrading from Joomla 2.5.18 to 2.5.20. I believe this also happened when I upgraded a different site from 2.5.18 to 2.5.19.
After upgrading, I checked the Joomla version. It says 2.5.20. I checked ExtensionsManager -> Warnings
There were none. I checked ExtensionsManager -> Database
Database table structure is up to date.
Database schema version (in
#__schemas): 2.5.20. Update version (in #__extensions): 2.5.20. Database driver: mysqli. 66 database changes were checked successfully. 41 database changes did not alter table structure and were skipped
- What is the Refresh Manifest Cache?
- Why is it causing the error? (I.E. What extension is likely to not be installed?)
- Is my installation safe? Should I upgrade again using the same upgrade package?
