    Have you got more infos about the cache options ? I didn’t found any documentations, like buttons “Flush JavaScript/CSS Cache”, “Flush Cache storage” ?
    Do you know exactly what happens for each button ? Thanks.

    great, but what does warning mean ” Cache storage may contain another data. Are you sure that you want flush it?” It sounds risky, is it?

    What happens when you flush the category images cache? I don’t want to do something that will get me in trouble

    Cache storage may contain another data. Are you sure that you want flush it? – this will clear everything in the cache so if you are using memcache it will flush everything including any other applications cache in there.

    flush the category images cache? – this makes magento re resize all the image in your catalogue, only worth doing if you’ve changed theme or something otherwise it will spank the cpu on the server as people browse the site

    Does refreshing the cache means removing all the files from var/cache folder?

    clear all cache after reindexing really make it faster. so recommended is to make reindexing in cron job and then also to clear cache should be placed in cron job, it will make magento system run faster.

      I just updated all my images through FTP and then nothing showed on front end. Then I noticed that Mage created a new products folder with a new cache subfolder. So I copied all the newly uploaded images into that folder and it solved the issue of no images being visible.
