I have many files in dir "cache" (because it is used by many phpbb3 forums).
Phpbb3 updates it late (after 30/40 minutes).
For example, when i create a category, i see it in "select forums" after 30/40 minutes; but if I delete (manually) all cache files, the category is shown immediately.
[b]How I use "cache" for many phpbb3 forums?[/b]
I edited all files where there is word "cache" and i added a "prefix".
For forum "test", cache files are: "test_tpl_etc"
For forum "abc", cache files are: "abc_tpl_etc"
