Here is what I just did to make sure I didn't skip any steps.
Confirmed permissions as follows
- session directory: 777
- templates/compile directory: 777
- templates: 777
- cache directory: 777
- cache_builders directory: 777
- cache_builders/custom directory: 777
- cache_builders/custom directory: 777
- cache_builder/custom files: 666
Deleted all files except any index.html files found from:
- sessions directory
- templates/compile directory
- templates directory
Then I used the cp to do a clear cache. The portal islands did not refresh.
When looking at the templates directory, I noticed a default subdirectory with a permission of 755 and files with permissions of 644. I did not do anything with that subdirectory or the files in that subdirectory.
Any other thoughts? Thanks.
