Joomla 1.5: I enabled SSL on the particular food selection. Recption menus item unsuccessful to change to https, which motivated me to google an answer. One forum stated the issue was resolved by clearing the cache. So, I visited tools/clean cache, selected all under "site" striking the remove button. This led to a swag of errors Body for every item I attempted to remove, saying
"Delete failed: 'index.html'"
Anybody know what is the happs?
If put forth 'Help' -> 'System info' -> 'Directory permissions' within the /administrator/ section of your site you need to get a listing of folders with information on whether or not they are writeable or otherwise.
I suspect your /cache/ folder is unwriteable - so you will have to change permissions around the folder under consideration to permit Joomla/PHP/Apache to remove the files from that folder.
Also see if cache folder is determined corectly. You are able to change cache folder location in "Site > Global configuration"
