Hello , my server runs 2.3.1 version of xoops .. and I want to upgrade to 2.4.5 .. after replacing the files to upgrade and running /upgrade , it keeps showing always this message

*Checking file and directory permissions...

The server must be given write access to the following files and folder
(i.e. chmod 777 directory_name on a UNIX/LINUX server)

* /home/riversom/xoops_data/caches is NOT writable.
* /home/riversom/xoops_data/caches/xoops_cache is NOT writable.
* /home/riversom/xoops_data/caches/smarty_cache is writable.
* /home/riversom/xoops_data/caches/smarty_compile is writable.
* /home/riversom/xoops_data/configs is NOT writable.

despite the fact that I changed permissions to those directories and made them writable ..

Any help will be apperciated

check to see in your mainfile.php if you have renamed these folders

if this is not the case then maybe the changes made by your ftp is not being saved correctly. You could make a small file called chmod.php, put the following text, upload to root and run from the browser. When done delete with ftp
