Dropdown-Menu "Cache Handler" shows only "File" – how to get "Redis", didn't found a Plugin?

@franz-wohlkoenig if I remember correctly it will only show redistributed if it is available in your server

yes confirm (same as postgres/mssql)

thanks for Info, @brianteeman and @alikon, i test local Mamp.

Php must have installed/enabled php-redis extension and a redis server available on a specified port.

I forget how flexible MAMP is with installing addons, but for those running a PHP build using Homebrew, same thing I posted in another issue works for installing/running Redis.

brew install redis
brew install phpxx-redis (replace xx with the PHP version you're using)
brew services start redis

Tested with Cache_Lite option in Cache Handler (here #18115 ). Work fine.

Unable to Clear Cache after Joomla 3.8 update

I've had Cache_Lite enabled on a VPS with Siteground. After the 3.8 Joomla update, I was unable to clear the cache by going to System/Clear Cache. I would receive "JFolder: :folder: Path is not a folder...." warning messages as well when I tried to "Delete All" in the Clear Cache screen.

I had posted this issue on Joomla.org and was directed to post my info here on this discussion.

I saw this github post earlier but wasn't sure it applied to my situation since I am not using redis. I went ahead and changed the two files but getting the same results. Lots of files remain, like this one:

2067144f1dcc5440579e377e476ea4509c8101_lock

So I set the handler from cache_lite to Files. Executed "Clean Cache" and all files in the cache were deleted, except these two:

Joomla\CMS\Component\ComponentHelper::load_lock
Joomla\CMS\Helper\LibraryHelper::loadLibraryjoomla_lock

I also see this warning on the same screen:

...../libraries/src/Cache/Storage/FileStorage.php on line 167
Warning: Invalid argument supplied for foreach() in ..../libraries/src/Cache/Storage/FileStorage.php on line 167

Along with these warning messages:

Joomla\CMS\Cache\Storage\FileStorage::_filesInFolder JFolder: :delete: Path is not a folder. Path: /...../cache/Joomla/CMS/Component/ComponentHelper::load_lock
Joomla\CMS\Cache\Storage\FileStorage::_folders JFolder: :delete: Path is not a folder. Path: /....../cache/Joomla/CMS/Component/ComponentHelper::load_lock

Hopefully some info you guys can use.

I'm not sure that you correctly replace patched files.
First, set cache handler to cache_lite, turn off cache for a while. Replace patched files again. Go to clear cache and delete all. Enable cache (cache_lite) - set conservative cache on.

Open home page in a new tab. Go to cache list and delete all cache. Please describe your result.

@csthomas, I have followed your instructions and can confirm that the issue on my end has resolved. The functions appear to be working properly.

Thank you for your assistance.
