What is wrong with your permissions? Why do you reset it? What do you mean by reset? What do yo do so that you have to reset permissions.
What are permissions set on your server for ow_pluginfiles, ow_userfiles, ow_smarty_template_c and ow_static folders?
They should be 777 permissions and it should be set recursively. Is that so on your side?
I will check this issue: n admin if i change a language value
then on search that language value again in admin can not find it
As to the permissions, as I noted you in some other topic, every time you uploaded new plugin or theme, the files which appeared on the server have the default permissions, like folders: 755 and files 644, this is a common practice for the servers, which controls that behavior.
